Unsupervised grouping of industrial electricity demand profiles: synthetic profiles for demand-side management applications, vol. 215 (Part A), pg. 118962.

In: Energy

  • 2020

DOI: 10.1016/j.energy.2020.118962

Demand side management is a promising alternative to offer flexibility to power systems with high shares of variable renewable energy sources. Numerous industries possess large demand side management potentials but accounting for them in energy system analysis and modelling is restricted by the availability of their demand data, which are usually confidential. In this study, a methodology to synthetize anonymized hourly electricity consumption profiles for industries and to calculate their flexibility potential is proposed. This combines different partitioning and hierarchical clustering analysis techniques with regression analysis. The methodology is applied to three case studies in Chile: two pulp and paper industry plants and one food industry plant. A significant hourly, daily and annual flexibility potential is found for the three cases (15% to 75%). Moreover, the resulting demand profiles share the same statistical characteristics as the measured profiles but can be used in modelling exercises without confidentiality issues.

Delivering a piece of proper and interesting information to tourists is always a challenge to deal with. It can be provided by many possible ways using traditional analogue materials (flyers, information table or paper maps) or using modern technologies such as web pages, mobile applications or an online multimedia tourist guide. One of online tourist guides is a travel guide created in Peregrinus Silva Bohemica project. This paper provides information about the final stage of such a guide from content and a technical point of view, to point out the complexity and usefulness of such a tool for tourists.

Unveiling the potential for combined heat and power in Chilean industry-A policy perspective, vol. 140, pg. 111331.

In: Energy Policy

  • 2020

DOI: 10.1016/j.enpol.2020.111331

Combined Heat and Power (CHP) has again become a key element in international energy and environmental policy, since it is one of the most promising methods of ensuring grid stability, making an energy system more flexible and environmentally friendly. This is particularly true in the case of Chile, which has an energy system that progressively introduced volatile renewable energy sources such as wind and solar energy. This scenario has led to the development of a new regulatory strategy and CHP flagship projects throughout the country. Despite this interest, there has been no analysis of CHP development or the impact of the latest regulatory changes on its evolution. This study presents an updated cadastre of the CHP facilities as of 2018, together with an analysis of its evolution in terms of an energy policy. From this cadastre, interviews with experts, and a review of the regulations and incentives, the study identifies the main policy barriers for CHP development in Chile. Furthermore, this study presents a series of challenges and recommendations for the country.

This paper deals with the problem of equipping 100 households in Lower Bavarian with sensors using different interfaces and protocols. This sensor set in the households is used in the context of the research project DeinHaus 4.0 of Deggendorf Institute of Technology. This project focuses on supporting technologies to enable elderly people to live as long as possible in their own house or apartment. Therefore, a set of sensors and Ambient Assisted Living (AAL) technologies are used to build a supporting system. Furthermore, the system collects, anonymizes and stores the sensor data for further technical and social analysis.

Risk prediction of wildlife-vehicle collisions comparing machine learning methods and data use, pg. 436-440.

DOI: 10.1109/ACIT49673.2020.9208946

Risk prediction of wildlife-vehicle collisions is crucial for reducing the abundant number of road accidents with wildlife worldwide. In this study, three different machine learning approaches - Gaussian Naive Bayes, Stochastic Gradient Descent, Random Forest - relying on recorded accident data, environmental, temporal and infrastructural parameters, are used to test the impurity of these parameters, and to predict the risk of wildlife-vehicle collisions. We use a dataset of one million police recorded accidents for southeastern Bavaria. Based on different approaches for feature engineering, we show the importance of data pre-processing and cleaning. With Random Forest, we receive a prediction accuracy of accidents of 86.7%. Additionally, the transferability of the three approaches is discussed, and possible ways of dynamic warnings via smartphone are presented.

DOI: 10.1109/ACIT49673.2020.9208843

Estimates of annual deer-vehicle collisions exceed one million incidences in Europe. Consequently, we were analyzing whether an animal’s experience and movement pattern close to roads can provide crucial information for accident prevention and mitigation measures. We applied an innovative approach using machine learning and step selection analyses to find rules and patterns in deer movement data for a better understanding of the spatio-temporal dynamics in wildlife-vehicle collisions. The rule tree indicated highest collision probabilities when the mean distance to a road of a roe deer tracking path was shorter than 192 meters and the roe deer crossed in more unfamiliar areas of its home range. The step selection function analysis revealed no obvious road avoidance and more road crossings in areas with less understory vegetation. Our results demonstrate the power of learned threshold values and step selection functions modelling results for a better understanding of the factors driving deer behavior in the vicinity of roads.

How to Better Find Historical Photographs in an Archive Geographic Driven Reverse Search for Photographs
  • 2019

Historical photographs are important sources for documenting the past of humanity. They can serve as evidence of our society’s history but are also objects of research themselves. Today, the standard format for describing the geographical origin of a photograph is to assign a geoname or point coordinate of the location of the photographer to the image. In view of historical photographs, we are dealing within this operation with spatial uncertainty. In most cases it is not possible to define the exact location of the photographer in form of coordinates in e.g. regions that afflicted strong environmental changes over time. The aspect of spatial uncertainty is also present, when describing the location of the photograph`s origin by a so-called geoname. A geoname can be comprehended to different extents. For example, it can name a region, a city or just a small part of a city. Therefore the question of the exact spatial origin cannot be answered by solely using a geoname. Such aspects of uncertainty in the localization of historical photographs complicate the retrievability in archives for spatially oriented search. Since the photographs cannot be found by entering search queries in the archive, their potential to serve as a data source for research cannot be fully exploited.

This paper argues that a digital infrastructure is vital to the work of cultural institutions today. In order to develop a well running system for smaller museums, which are hardly ever center of focus of donating companies and sponsors, we develop four measures, an integrated content management and digital signage system, an application for smart phones and a 3D city model, that will allow the visitors to connect with the city's history, virtually and physically.

Modell zur Übertragbarkeit der Ergebnisse aus der Feldstudie auf größere RegionenBerücksichtigung aktueller technischer und organisatorischer Rahmenbedingungen beim Einsatz autonomer Shuttlebusse, pg. 179-197.
  • 2019
Heutzutage sind automatisierte Shuttlebusse noch eher selten im öffentlichen Straßenverkehr zu finden. Feldstudien sind daher unumgänglich, um eine Analyse der existierenden Möglichkeiten und nötigen technischen Maßnahmen zur Integration dieser Fahrzeuge in den öffentlichen Personennahverkehr (ÖPNV) zu erproben. Da es sowohl technisch als auch rechtlich noch Einschränkungen der Nutzung automatisierter Fahrzeuge gibt, stellt sich die Frage, ob potenzielle Routen, die diesen Rahmenbedingungen gerecht werden, automatisiert ermittelt werden können. Allerdings ist die Erstellung eines Modells zur Identifikation von Strecken für automatisierte Fahrzeuge unter den gegebenen rechtlichen Randbedingungen noch nicht näher betrachtet worden. Die hier verwendeten Parameter sind auf Grundlage der Ergebnisse einer Studie in Bad Birnbach, Bayern entstanden. Im Vergleichsraum Bayern wurden ca. 100 Strecken identifiziert, auf welchen man einen automatisierten Shuttlebus im derzeitigen technisch-rechtlichen Rahmen weiter testen könnte. Die sich stetig weiterentwickelnde Technologie und die teils unvollständige Attribuierung der verwendeten Daten (offizielle Verkehrsdaten ATKIS, OpenStreetMap aus dem Jahr 2018) erfordern eine Überprüfung der Ergebnisse vor Ort sowie eine laufende Fortschreibung des Modells.

Can Geoinformation Help to Better Protect Informal Settlements? - A Concept For the City of Medellín, pg. 115-120.

In: Gi4DM 2019 – GeoInformation for Disaster Management. null (The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences)

New contributions to disaster research need to address the increasing vulnerability of informal settlements in a changing climate situation. Informal settlements are frequently built in hazardous areas and are often left out of traditional disaster risk management concepts. Hence, formal and informal societal structures, as well as technical systems to warn against, handle or mitigate natural hazards, need to evolve. Within the project Inform@Risk we are addressing these issues based on a case study in Medellín (Colombia). Here, as a result of civil conflicts informal dwellings were partly constructed by people displaced from rural areas. They are mainly located in the urban peripheral areas along steep and unstable slopes, where the resettlement of all inhabitants at risk of landslides is unfeasible. This contribution presents the technical infrastructure and the concept to incorporate geodata from different sources in an integrated landslide early warning system for some selected informal settlements of Medellin. Special attention is given to possibilities on how building societal institutions, supported by information systems, increases local resilience. Using geoformation as a basis, we will combine classical participatory planning methods with digitally assisted concepts. These include combining satellite and UAS based remote sensing data with terrestrial sensor networks, crowd sourcing and citizen science to collect volunteered geographic information about the settlement and its environmental parameters, as well as distribute this information and disseminate warnings to the local population.

Industry, flexibility, and demand response: Applying German energy transition lessons in Chile, vol. 54, pg. 12-25.

In: Energy Research & Social Science

  • 2019

DOI: 10.1016/j.erss.2019.03.003

Demand side management (DSM) contributes, among its other purposes, to provide stability and flexibility to energy systems that include a high proportion of variable renewable energy in pioneer countries and those which recently began their energy transition. Among DSM policies, implementation of measures and mechanisms for a demand response (DR) is not a trivial matter. This study presents a review and comparative analysis of the major energy policy developments in Germany and Chile. Based on i) the relevance of the industry sector in both countries, ii) the difficulty in implementing the regulatory framework and iii) the importance given to the industrial customers in the German legislation and DR literature, the following analysis will focus on both medium and large industrial customers. The goals are to review the challenges in untying the full DR potential of the productive industry and to provide recommendations for the promotion of DR in Chile. Emphasis is placed on the lessons learned in fitting the wide potential of DR in the German electricity markets. A review of the successes and failures of the German experience reveals the potential risk that poor policy implementation can have in both the short and long term.

Hybrid renewable energy systems to supply electricity to self-sufficient residential buildings in Central Europe, pg. 321-326.
  • 2019

DOI: 10.1016/j.egypro.2019.01.096

This work evaluates potentials of photovoltaic and battery systems with additional micro-generation wind turbines (10.5 kW) to cover electricity demand of residential users in two countries in Central Europe. It relies on high-resolution regional reanalysis data and a techno-economical optimization model. Maps showing the number of wind turbines, photovoltaic and battery systems sizes necessary to supply electricity for clusters of electricity self-sufficient single-family houses across Germany and the Czech Republic are generated. No general trends that apply for the two countries concerning the relation between the sizes of the different technologies were identified. However, it was possible to determine several large areas where the inclusion of small wind turbines decreases the total system costs and considerably reduces the required storage capacities. Results are discussed and compared to previous work on self-sufficient single-family houses.

Assessment of on-site steady electricity generation from hybrid renewable energy systems in Chile, vol. 250, pg. 1548-1558.

Chile has an immense renewable energy potential but its integration into the energy system constitutes a major challenge. The country has a complex topography that is expressed by a divided national grid with almost isolated subsystems and wide differences in the availability of renewable energy resources. The present study aims at evaluating the potentials of combining solar power, wind power and storage systems to provide steady loads already from the generation source. The analysis relies on an optimization model to size hybrid renewable energy systems and 10 years of weather data from the brand new ERA5 global reanalysis. Multiple scenarios are calculated and intercompared for all possible locations across the country. These scenarios include system sizing considering hourly weather data for the period 2008–2017 and for one year without major weather extreme events. In both analyses, the results are calculated for systems that generate 1 MWh of electricity at every time step and systems that have certain intraday flexibility. Results show that the necessary generation and storage capacities to provide a steady energy output are very high even for areas with exceptionally high renewable energy potential (in the Atacama desert the system configuration requirements could reach 10 MWp of photovoltaics and 10 MWh of storage). Intraday flexibility has direct effects on these results by reducing the total size of the systems but the effects on the sizes of the installations of the particular technologies depend on the individual geographical location.

A spatially explicit assessment of middle and low voltage grid requirements in Bavaria until 2050, vol. 13, pg. 88-97.

  • 2019

DOI: 10.2478/geosc-2019-0008

The energy transition towards high shares of renewables and the continued urbanization process have a direct and strong impact on the shape and characteristics of the electricity transmission and distribution systems. At the continental and national scale, improved high voltage grids should allow the transmission and balance of electricity from hot-spots of variable renewable energy generation installations to demand centres. At the regional and municipal scale, the medium and low voltage grids should be capable of bringing sufficient electricity to users and allow the integration of distributed renewable generation installations. While data on the transmission systems is widely available, spatial and attribute data of the medium and mainly the low voltage grids are scarce. Additionally, while there are plenty of studies on the requirements of the grid to allow the energy transition, there is very little information on the necessary transformation of the grid due to changes generated by the expected urbanization process. This study relies on a data set that estimates the topology of the medium and low voltage grids of Bavaria (Germany) as well as data from the LUISA territorial modelling platform of the European Commission to calculate key figures of grid requirements depending on population and land use for the current case and the decades to come. Typologies of grid requirements are proposed based on a statistical analysis of population and land use data of each square kilometre of the federal state. These typologies are extrapolated to changes in the structure of settlements that are expected in the years 2030 and 2050. Results are presented using maps with expected absolute values of grid requirements and their temporal changes for each square kilometre of the project area. Grid requirements are expected to increase in cities and to be reduced in most of the rural areas. The largest changes are expected to take place in the suburbs of the major cities.

Assessment of on-site steady electricity generation from renewable energy sources in Chile, pg. 1099-1104.

DOI: 10.1016/j.egypro.2019.01.266

Chile has an immense renewable energy potential but their integration in the energy system constitutes a major challenge. The complex topography of the country, the isolation of the different electric grids and the variability of renewable energy sources, makes energy transmission from locations with high variable renewable power generation potential to the demand centres not an easy task. The present study aims at assessing the potential of combining solar power, wind power and storage systems to provide steady loads already from the source. Such a combination should take advantage of complementarity between variable renewable sources and serves to simplify their integration in the energy system. The analysis relies on an optimization model to size hybrid renewable energy systems and 10 years of weather data from the brand new ERA-5 reanalysis. Necessary system sizes to constantly generate 1 MWh of electricity for every hour during the period 2008-2017 are calculated for all possible locations across the country. The results show that the necessary generation and storage capacities to provide a steady energy output are very high even for areas with exceptionally high renewable energy potential.

Energy Modelling in Rural Areas with Spatial and Temporal Data in Germany and Czech Republic, pg. 220-227.
  • 2019

One of the major challenges for the energy transition is to reconcile variable renewable energy production with stochastically changing energy demand including the pursued changes in e.g. transport like electro mobility. This requires smart systems that should be designed to minimize balancing and transmission costs. The design and modelling of such systems requires high resolution energy generation and demand data, which usually either do not exist or is not available. Methodologies to address this lack of data populate scientific literature but its replicability is limited by an inadequate level of detail in the description of the methodologies and to a larger extent by the absence or low quality of basic data. This manuscript summarizes severalyears of research in energy modelling using Geographical Information Systems as well as spatial and temporal data of the rural areas in Bavaria (Germany) and the Czech Republic. Data requirements for energy demand and energy supply including different types of users and technologies are addressed. Irreconcilable data gaps are presented, examples to fill data gaps as well as recommendations for future necessary developments are provided

Potential Analysis of Hybrid Renewable Energy Systems for Self-Sufficient Residential Use in Germany and the Czech Republic, vol. 12, pg. 4185.

In: Energies

  • 2019

DOI: 10.3390/en12214185

Independence from the power grid can be pursued by achieving total self-sufficient electricity supply. Such an energy supply model might be particularly interesting for settlements located in rural areas where enough space is available for energy generation installations. This article evaluates how and at what cost electricity demand of residential users across Germany and the Czech Republic could be covered by hybrid renewable energy generation systems consisting of photovoltaics, micro-generation wind turbines and batteries. High-resolution reanalysis data are used to calculate necessary system sizes over a large area by simultaneously accounting for the temporal variability of renewable energy. For every potential location in the research area, the hybrid system requirements for clusters of 50 self-sufficient single-family houses are calculated. The results indicate no general trend regarding the size of the respective technologies, although larger areas where PV-wind power complementarity enables lowering the total system costs and required storage capacities were determined. Assuming that the cluster of households could be constituted and depending on the location, the total installation and operation costs for the proposed systems for a lifetime of 20 years range between EUR 1.8 Million and EUR 5 Million without considering costs of financing. Regions with the lowest costs were identified mainly in the south of Germany.

Do Crash Barriers and Fences Have an Impact on Wildlife-Vehicle Collisions? An Artificial Intelligence and GIS-Based Analysis, vol. 8, pg. 66.

  • 2019

DOI: 10.3390/ijgi8020066

Wildlife–vehicle collisions (WVCs) cause significant road mortality of wildlife and have led to the installation of protective measures along streets. Until now, it has been difficult to determine the impact of roadside infrastructure that might act as a barrier for animals. The main deficits are the lack of geodata for roadside infrastructure and georeferenced accidents recorded for a larger area. We analyzed 113 km of road network of the district Freyung-Grafenau, Germany, and 1571 WVCs, examining correlations between the appearance of WVCs, the presence or absence of roadside infrastructure, particularly crash barriers and fences, and the relevance of the blocking effect for individual species. To receive infrastructure data on a larger scale, we analyzed 5596 road inspection images with a neural network for barrier recognition and a GIS for a complete spatial inventory. This data was combined with the data of WVCs in GIS to evaluate the infrastructure’s impact on accidents. The results show that crash barriers have an effect on WVCs, as collisions are lower on roads with crash barriers. In particular, smaller animals have a lower collision share. The risk reduction at fenced sections could not be proven as fenced sections are only available at 3% of the analyzed roads. Thus, especially the fence dataset must be validated by a larger sample number. However, these preliminary results indicate that the combination of artificial intelligence and GIS may be used to analyze and better allocate protective barriers or to apply it in alternative measures, such as dynamic WVC risk-warning.

Mapping minimum technical requirements for electricity self-sufficiency of single-family houses using regional reanalysis data and satellite imagery derived data, vol. 20

In: Geophysical Research Abstracts

  • 2018
Decreasing prices of photovoltaic (PV) and electricity storage systems have popularized the idea of independency from the grid among household's owners. The basic idea is simple: on the one side, PV installations can easily fit in building's roof-tops while producing more energy per year than a household would require; on the other side, the temporal mismatch between energy generated by the PV system and the electricity consumed by the household can be corrected with storage systems. In theory, this basic concept would require the examination of long time series of weather data and an optimization model in order to find a system configuration that actually fulfils the requirements of a household in a particular location. In practice, such detailed studies would be too expensive for small-scale installations and contractors take system sizing decisions based on empirical values or general sizing guidelines. Motivated by the project CrossEnergy, a research project that studies the future of the energy system in rural areas at the border between Germany and Czech Republic, and by the publication of the COSMO-REA high resolution regional reanalysis data sets for Europe in 2017, this study presents a methodology to generate maps indicating minimum battery and PV sizes for self-sufficient single family houses (SFHs). The methodology consist of three parts. First, settlement data extracted from the LUISA Territorial Modelling platform of the European Commission is used together with standard load profiles to generate spatiotemporal data sets of electricity demand for rural and low density urban areas. Second, spatiotemporal data sets of PV potential are generated based on a) a technical PV model, b) instantaneous solar irradiance and temperature data from the COSMO-REA regional reanalysis data, and c) snow cover data from the Land Surface Analysis Satellite Applications Facility. Third, a linear optimization model, relying on the data sets of the two previous parts, serves to define PV and battery systems sizes and to generate the corresponding maps. The resulting maps cover Germany and Czech Republic and are generated for multiple technical and weather dependent scenarios. The results show how complicated it could be to achieve a complete independence from the grid in certain locations and offer a scientifically based source of information for sizing PV-battery systems in the two countries. An outlook how to apply the methodology to the whole CORDEX Euro area and for future work is provided.

Assessing variables of regional reanalysis data sets relevant for modelling small-scale renewable energy systems

In: European Geosciences Union (EGU) General Assembly 2018

  • 2018

Data that allow the characterization of short-term and inter-annual variability of renewable energy resources availability are becoming highly valuable for energy system modellers. Global reanalysis data provide long time series of records without gaps and full spatial coverage at no cost for the final user. However, these exhibit coarse spatial resolution. The COSMO-REA6 and COSMOS-REA2 regional reanalysis for Europe overcome this limitation by increasing the resolution of the reanalysis to six and two kilometres respectively. This work presents an assessment of solar radiation and wind speed variables of these data sets that were available to the public in January 2018. This assessment is performed using data of the Bavarian agro-meteorological network and the Czech Hydrometeorological Institute. Eight accuracy indicators for hourly data in the period 1995–2015 are calculated. Widely used indicators such as the Pearson's correlation coefficient in some cases reach values above 0.82 for wind speeds and above 0.92 for global horizontal irradiance. The mean bias error is consistently better than ± 9.3 W/m2 for the full set of irradiance data, ±25.1 W/m2 for only day-time irradiance data and is, with a few exceptions, lower than ± 1 m/s for the wind speed data.

Assessing regional reanalysis data sets for planning small-scale renewable energy system
  • 2018

An accurate resource availability estimation is vital for proper location, sizing and economic viability of renewable energy plants. Large photovoltaic (PV) and wind installations undergo a long and exhaustive planning process that would imply unacceptably high costs for developers of small-scale installations. In a context of abolition of feed-in tariffs, electricity feed-in restricted by grid capacity constraints and storage systems being commercialized at lower costs, the acquisition of high quality solar radiation and wind speed data becomes important also for planners of small scale installations. These data allow the characterization of short-term and inter-annual variability of the resources availability. Global reanalysis data sets provide long time series of these variables with temporal resolutions that can be as high as one hour and at no cost for the final user. However, due to the coarse spatial resolution and relatively low accuracy these products only provide an inferior alternative for data retrieval compared to e.g. satellite derived radiation data sets or advanced interpolation methods for wind speed data. The COSMO-REA6 and COSMOS-REA2 regional reanalysis overcome this limitation by increasing the resolution of the reanalysis to six and two kilometres respectively. The accuracy of these data sets for variables with high relevancy for meteorology, such as rainfall, has been assessed with satisfactory results but an independent evaluation for variables relevant for renewable energy generation has not been performed yet. This work presents an assessment of the variables of these data sets that have been made available to the public until November 2017. This assessment is performed for the area of the federal state of Bavaria in Germany and whole Czech Republic using data of the Bavarian agro-meteorological network and the Czech Hydrometeorological Institute. Accuracy indicators are calculated for horizontal global radiation or cloud coverage (depending on data availability from the weather stations) and wind speeds at 10 meters height. While there are important differences between weather stations and cloud coverage data, the results for wind speeds and global solar irradiance are satisfactory for most of the locations. For certain locations widely used indicators such as the Pearson's correlation coefficient reach values above 0.8 for wind speeds and above 0.9 for global solar irradiance and the mean biased error is consistently lower than 10 W/m2 and can be as low as 0.3 W/m2 for the irradiance data and is, with a few exceptions, lower than 2 m/s in Germany and lower than 1 m/s in the Czech Republic for wind speed data. A total of eight indicators for the hourly data in the period between 1995 and 2015 are calculated, presented, discussed and compared against international literature dealing with data accuracy for solar irradiance and wind speed data sets.

A review of spatial localization methodologies for the electric vehicle charging infrastructure, pg. 1-17.

In: International Journal of Sustainable Transportation

DOI: 10.1080/15568318.2018.1481243

With view to the high share of the transport sector in total energy consumption, e-mobility should play an important role within the transition of the energy systems. Policymakers in several countries consider electric vehicles (EV) as an alternative to fossil-fueled vehicles. In order to allow for the development of EV, the charging infrastructure has to be set up at locations with high charging potential, identified by means of various criteria such as demand density or trip length. Many methodologies for locating charging stations (CS) have been developed in the last few years. First, this paper presents a broad overview of publications in the domain of CS localization. A classification scheme is proposed regarding modeling theory and empirical application; further on, models are analyzed, distinguishing between users, route or destination centricity of the approaches and outcomes. In a second step, studies in the field of explicit spatial location planning are reviewed in more detail, that is, in terms of their target criteria and the specialization of underlying analytical processes. One divergence of these approaches lies in the varying level of spatial planning, which could be crucial depending on the planning requirements. It is striking that almost all CS locating concepts are proposed for urban areas. Other constraints, such as the lack of extensive empirical EV traffic data for a better understanding of the driving behavior, are identified. This paper provides an overview of the CS models, a classification approach especially considering the problem’s spatial dimension, and derives perspectives for further research.

Archives of historical photographs have a great potential for "geo- or spatial sciences", for they can provide highly relevant visual data on historical landscapes, populated places and settlement structures, including those now destroyed. Processing of these archives represents many challenges, among them the application of geoinformatic concepts and information technologies. The article presents the example of geo-referencing, crowdsourcing, and other computer-based technologies applied to the archival photographs of today-destroyed sites on the Czech – Bavarian border, where many villages, farm sites and monuments were destroyed in the 1950s or abandoned as a consequence of post-WWII development. In the situation of dramatically changing landscape and land use, historical photographs are an important source of documentation for both research and virtual reconstruction of disappeared places, landscape, and society.

Electricity self-sufficiency of single-family houses in Germany and the Czech Republic, vol. 228, pg. 902-915.

DOI: 10.1016/j.apenergy.2018.06.118

Motivated by a research project that studies the future of the energy system in rural areas at the border between Germany and the Czech Republic, and by the publication of the COSMO-REA high-resolution regional reanalysis data sets for Europe in 2017, this study presents a methodology for generating maps indicating minimum battery and photovoltaics sizes for self-sufficient single-family houses. The methodology consists of three subsequent parts: First, spatiotemporal data sets of electricity demand for single-family houses in rural and low-density urban areas are generated. Second, spatiotemporal data sets of photovoltaics potential are computed based on (a) a technical photovoltaics model, (b) two decades of hourly solar irradiance and temperature data, and (c) snow cover data from the Land Surface Analysis Satellite Applications Facility. Third, a linear optimization model serves to define photovoltaics and battery systems sizes and to generate the corresponding maps. The resulting maps cover Germany and the Czech Republic and are generated for 18 technical and weather-dependent scenarios. The results show how challenging it could be to achieve complete independence from the grid in certain locations. Especially relevant for the sizing of the systems are long periods (several days in a row) of low photovoltaic energy generation due to overcast sky conditions or snow cover of the panels. Furthermore, the results offer a scientifically based source of information for sizing photovoltaics and battery systems in the two countries.

Technical, Economical and Social Assessment of Photovoltaics in the Frame of the Net-Metering Law for the Province of Salta, Argentina, vol. 9

In: Energies

  • 2016

DOI: 10.3390/en9030133

Central and Northern Argentinean regions possess a high potential for the generation of solar energy. The realization of this potential is an alternative to alleviate the strong dependence on imports of fossil energy and to reduce the CO2 emissions of the country. However, the adoption of photovoltaics (PV) is still in an incipient state. It is undermined by a context of heavily subsidized electricity prices, high equipment and installation costs and a lack of information, training and experience in handling PV technology. This paper presents a techno-economical assessment of the application of the recently enacted net-metering law for promoting renewable energies (RE) in the Province of Salta (Northwest Argentina) for the case of PV. The assessment shows under which conditions and for which types of consumers it is profitable to adopt PV in the context of the law. This analysis is supported by a participatory planning approach as a study of stakeholders’ attitudes towards RE, intentions to adopt PV and their knowledge about the law. The results of this study and the economical analysis serve to provide recommendations aimed at increasing the level of PV adoption in the province.

Comparison of satellite imagery based data, reanalysis data and statistical methods for mapping global solar radiation in the Lerma Valley (Salta, Argentina), vol. 99, pg. 57-68.

  • 2016

DOI: 10.1016/j.renene.2016.06.042

Global solar radiation is the most important factor to determine the energy generation potential of photovoltaic (PV) plants. In Argentina only a small number of ground measured data of global solar radiation exists. Researchers and PV developers have to use statistical methods or satellite imagery to handle this lack of information and provide an estimation of global solar radiation for a particular location. In this paper global solar radiation data sources for the Lerma valley are explored in order to assess which data set is best suitable for future studies of photovoltaic energy generation potential at the best possible spatial and temporal resolution. We evaluate global solar radiation from the reanalysis data set provided by the European Centre for Medium-Range Weather Forecasts (ECMWF) and the Meteosat second generation derived data set provided by Land Surface Analysis Satellite Applications Facility (LSA-SAF). These are compared with each other, with data generated using statistical methods and with data from a pyranometer. The results show that the data from LSA-SAF fit best to the ground measurements. This together with a high spatial and temporal resolution makes the LSA-SAF data a satisfactory alternative to compensate the lack of global solar radiation data available for the study area.

FOSS4G-based energy management system for planning virtual power plants at the municipal scale, pg. 159-164.

In: Geomatics Workbooks

  • 2015

The exploitation of renewable energy sources (RES) implies a transformation of the current energy supply infrastructure towards a spatially decentralized structure. This process has a significant impact on the use of space because energy is no longer generated far away from the demand, but it can be provided directly on-site. Hence, geographic information systems (GIS) have become a well established tool for the determination of sites for RES plants for heat and electricity generation. However, planning energy supply systems with a high share of RES, such as virtual power plants (VPPs), requires to consider also the temporal variation of the generation profiles of RES and the local energy demand. This paper presents the work in progress on a FOSS4G-based tool for the spatio-temporal modeling of municipality wide VPPs. The detailed simulation of potential RES-based supply alternatives and energy demand allows to identify suitable locations and to define the optimal size and technical characteristics of the individual RES energy generation plants in a VPP. This information can serve to assess technical renewable energy potentials at the municipal scale and to design a RES deployment roadmap customized to better fulfil the local energy demand.

Integrated spatial and energy planning has become a major field of interest to meet the current renewable energy share expansion and CO2 emissions reduction targets. Geographic Information Systems (GIS) play a considerable role in supporting decision making in this field. Solar potential maps are a popular strategy to promote renewable energy generation through photovoltaic (PV) panel installations at city and municipal scales. They indicate the areas of roofs that would provide the maximum amount of energy in kW h per year. These are often used to suggest “optimal locations” for PV-panels and/or recommend system sizes to achieve a certain level of yearly autarchy. This approach is acceptable if PVs have only a minor share in the local energy supply system. However, increased PV-penetration can lead to instability of the local grid, create hazards for the security of the supply, and considerably escalate the storage and system back-up requirements. To obtain a proper understanding of the consequences for the local energy balance when selecting or rejecting a certain installation, examining the hourly and intra-hourly time series of the potential energy generation from PVs is necessary. This paper introduces a GIS-based procedure to estimate the potential PV-electricity generation time series for every roof-top section within a study area using open source software. This procedure is complemented by a series of strategies to select suitable PV-installations considering the time series analysis of supply and demand. Furthermore, thirteen technical indicators are considered to evaluate the PV-installation sets selected with every strategy. The capabilities of the procedure are tested using data from a German rural municipality. The proposed procedure constitutes an efficient and accessible way to assess solar potentials at the municipal scale and to design roof-top PV exploitation plans, which are more appropriate to fulfill the local energy requirements.

Spatiotemporal modeling for assessing complementarity of renewable energy sources in distributed energy systems, pg. 147-154.

Spatial assessments of the potential of renewable energy sources (RES) have become a valuable information basis for policy and decision-making. These studies, however, do not explicitly consider the variability in time of RES such as solar energy or wind. Until now, the focus is usually given to economic profitability based on yearly balances, which do not allow a comprehensive examination of RES-technologies complementarity. Incrementing temporal resolution of energy output estimation will permit to plan the aggregation of a diverse pool of RES plants i.e., to conceive a system as a virtual power plant (VPP). This paper presents a spatiotemporal analysis methodology to estimate RES potential of municipalities. The methodology relies on a combination of open source geographic information systems (GIS) processing tools and the in-memory array processing environment of Python and NumPy. Beyond the typical identification of suitable locations to build power plants, it is possible to define which of them are the best for a balanced local energy supply. A case study of a municipality, using spatial data with one square meter resolution and one hour temporal resolution, shows strong complementarity of photovoltaic and wind power. Furthermore, it is shown that a detailed deployment strategy of potential suitable locations for RES, calculated with modest computational requirements, can support municipalities to develop VPPs and improve security of supply.

Modell zur regionalen Optimierung der Stromversorgung aus Photovoltaik, vol. 1, pg. 14-26.

Motiviert durch die Transformation des Energiesektors in Richtung dezentraler erneuerbarer Energien präsentiert dieser Beitrag eine innovative Methodik zur qualitativen Verbesserung der Vorhersage von Stromerträgen aus der Photovoltaik, um darauf aufbauend optimale regionale Versorgungsstrukturen modellieren zu können. Die Wetterabhängigkeit der Photovoltaik und die damit einhergehende hohe Variabilität der Erzeugung bereiten gerade bei regionalen Versorgungskonzepten Probleme, die Versorgungssicherheit gewährleisten zu können. Die Lösung wird häufig in der Verwendung von elektrischen Speichern und anderen intelligenten Erzeugern und Verbrauchern gesehen. Das hier vorgestellte Modell zur regionalen Optimierung der Stromversorgung aus Photovoltaik verbessert zum einen die Prognose der Stromerzeugung aus Photovoltaik hinsichtlich sowohl eines räumlichen als auch zeitlichen Aspektes. Zum anderen zeigt das „Spatial Energy Management Model“ einen Weg auf, wie sich der Stromnachfrage angepasste Ausbaustrategien der Photovoltaik ermitteln lassen. Anhand der Ortschaft Löwendorf im Landkreis Cham wird das Modell exemplarisch angewendet und verschiedene Szenarien für ein regionales Energiemanagement entwickelt. Die Ergebnisse zeigen im Vergleich zur gängigen Praxis des Photovoltaikausbaus, vornehmlich orientiert an der Maximierung individueller wirtschaftlicher Rentabilität, deutliche Verbesserungspotenziale. So kann für die Ortschaft Löwendorf durch die Anwendung des Modells bei gleichbleibender technologischer Durchdringungsrate sowohl die Höhe der installierten Photovoltaikleistung (kWp) als auch die notwendige Speicherkapazität (Wh) verringert werden. Die anhand des Modells erzielten Ergebnisse dienen der weiteren wissenschaftlichen Ausarbeitung von intelligenten Versorgungssystemen wie virtuellen Kraftwerken oder Smart Grids. Gleichzeitig liefert das Modell anwendungsorientiert wichtige Erkenntnisse für Energieversorger, für Kommunen oder die Infrastrukturplanung, um eine nachhaltige dezentrale Energieversorgung erfolgreich umzusetzen. Motivated by the transformation of the energy sector towards decentralized renewable energies, this paper presents an innovative methodology for improving the quality of the prediction of energy yield from photovoltaics in order to model optimal regional supply structures. The weather dependency of photovoltaics and the concomitant high variability of generation cause problems for supply concepts at a regional scale with regard to ensuring security of supply. The solution is often seen in the use of electrical storage and other smart producers and/or consumers. The model for regional optimization of power from photovoltaics which is presented here first of all improves the forecast of electricity from photovoltaics in terms of a spatial and also a temporal aspect. Secondly, the „Spatial Energy Management Model“ shows a methodology on how to identify expansion strategies of photovoltaics which are adapted to the energy demand. A case study of the village of Löwendorf, located in the district of Cham, exemplifies the application of the model and develops different scenarios for a spatial energy management on a regional scale. The results indicate significant potential for improvement compared to the standard practice of the photovoltaic development, which is mainly oriented to the maximization of individual economic profitability. Thus, the amount of installed photovoltaic power (kWp), as well as the necessary storage capacity (Wh) can be reduced for Löwendorf by applying the model with constant technological penetration. On the one hand, the results achieved with the model serve to further scientific development of intelligent supply systems such as virtual power plants or smart grids. On the other hand, the model provides important application-oriented insights for utilities, municipalities or infrastructure planning in order to successfully implement a sustainable decentralized energy supply.

Recommendations for user-specific enhancement of flood maps, vol. 12, pg. 1701-1716.

In: Natural Hazards and Earth System Sciences

  • 2012

The European Union Floods Directive requires the establishment of flood maps for high risk areas in all European member states by 2013. However, the current practice of flood mapping in Europe still shows some deficits. Firstly, flood maps are frequently seen as an information tool rather than a communication tool. This means that, for example, local stocks of knowledge are not incorporated. Secondly, the contents of flood maps often do not match the requirements of the end-users. Finally, flood maps are often designed and visualised in a way that cannot be easily understood by residents at risk and/or that is not suitable for the respective needs of public authorities in risk and event management. The RISK MAP project examined how end-user participation in the mapping process may be used to overcome these barriers and enhance the communicative power of flood maps, fundamentally increasing their effectiveness. Based on empirical findings from a participatory approach that incorporated interviews, workshops and eye-tracking tests, conducted in five European case studies, this paper outlines recommendations for user-specific enhancements of flood maps. More specific, recommendations are given with regard to (1) appropriate stakeholder participation processes, which allow incorporating local knowledge and preferences, (2) the improvement of the contents of flood maps by considering user-specific needs and (3) the improvement of the visualisation of risk maps in order to produce user-friendly and understandable risk maps for the user groups concerned. Furthermore, "idealised" maps for different user groups are presented: for strategic planning, emergency management and the public.

Flood risk map perception through experimental graphic semiology, pg. 705-714.

Flood risk map perception through experimental graphic semiology S. Fuchs Institute of Mountain Risk Engineering, University of Natural Resources and Applied Life Sciences, Vienna, Austria W. Dorner & K. Spachinger Department of Civil Engineering, University of Applied Sciences, Deggendorf, Germany J. Rochman & K. Serrhini UMR CNRS 6173, University of Tours, Tours, France The procedure of risk assessment emerged as an appropriate tool to analyse the impacts resulting from natural hazards. However, despite from a considerable amount of approaches and guidelines, only little work has been carried out with respect to the harmonisation of risk mapping, the information necessary, and the required quantification of possible impacts on decision-makers. A particular gap exists with respect to the perception of information provided in risk mapping for different stakeholder groups. Within the RISKCATCH project, risk maps were created for catchments located in the Alps and the related forelands. Based on the assessment of historical and possible future development of hazard, values at risk and vulnerability, these maps were created on different scales using scenario technique. The information cre- ated was evaluated by presenting the maps to several stakeholder groups, above all political decision makers, practitioners and laypersons from European countries, using the method of graphic semiology. As a result, pos- sible improvements in design and content of such information were deduced. The respective hydrological processes (precipitation, land use, geomorphology) and the rivers (structure, flood plain and flood defence) were analysed on a regional and temporal scale for three catchments in the Austrian Alps and two catchments in the German alpine foreland. Existing data of synthetic floods derived from hydrological models in combination with stream routing was linked with data of real flood and debris flow events to analyse the relations between precipitation and the development of hazards in the river system. Based on the modelling results of defined design events, the associated damage potential was assessed. Multi- temporal data on damage of previous inundations and data on the associated damage potential in the test sites was collected and edited for the use within a GIS-environment. The elements at risk—which were defined as those buildings within the test sites located in endangered area—were analysed with respect to their spatial location and extension using GIS. Intersecting this information, risk maps were generated on different scales in order to analyse possible improvements in information content and design. To quantify risk perception, the maps were presented to a group of stakeholders from different European countries. The method used was based on the approach of experimental graphic semiology, reversing the tradi- tional communication pattern from transmitter to receiver. Starting from receiver, the maps were presented to the test persons using an ophthalmic device for the record of eye movements during picture reading. The test was accompanied by a specific survey; hence, the cognitive perception of risk maps was evaluated. All maps were presented to the test persons for a relatively short time period to identify the most attractive components of each map. The eye movements were subsequently statistically analysed in order to assess patterns of visual perception for each map and to study the reading behaviour for text elements included in the maps. The visual strategies of each test person were quantified. The study resulted in guidelines of how to include information on natural hazard risk for different stakehold- ers, in particular with respect to visual information contained in risk maps. Thus, the results of the study can be used by administrative bodies for communication strategies within the concept of integral risk management, in particular with respect to non-structural flood mitigation.

Evaluating cartographic design in flood risk mapping, vol. 8, pg. 52-70.

In: Environmental Hazards

  • 2009

In order to mitigate flood hazards and to minimize associated losses, technical protection measures have been additionally and increasingly supplemented by non-technical mitigation, i.e. land-use planning activities. This is commonly done by creating maps which indicate such areas by different cartographic symbols, such as colour, size, shape and typography. Hazard and risk mapping is the accepted procedure when dealing with natural hazards and is therefore required in the European Member States in order to meet the demands of the European Flood Risk Directive. However, available information is sparse concerning the impact of such maps on different stakeholders, i.e. specialists in flood risk management, politicians and affected citizens. The lack of information stems from a traditional approach to map production which does not take into account specific end-user needs. In order to overcome this information shortage the current study used a circular approach such that feedback mechanisms originating from different perception patterns of the end user would be considered. Different sets of small-scale as well as large-scale risk maps were presented to different groups of test persons in order to (1) study reading behaviour as well as understanding and (2) deduce the most attractive components that are essential for target-oriented communication of cartographic information. Therefore, the method of eye tracking was applied using a video-oculography technique. This resulted in a suggestion for a map template which fulfils the requirement to serve as an efficient communication tool for specialists and practitioners in hazard and risk mapping as well as for laypersons. Taking the results of this study will enable public authorities who are responsible for flood mitigation to (1) improve their flood risk maps, (2) enhance flood risk awareness and, therefore, (3) create more disaster-resilient communities.

Environmental economic aspects of river basins and their catchmentIdentification and quantification of flood related land use externalities
  • 2009
This thesis investigates a common problem of land use impacts on flood damage costs on a catchment scale. It does this through a particular case study, to quantify the technical upstream-downstream dependencies and highlights the externalities through hydroeconomic analysis of flood damages and mitigation costs. The substantive content of the project is cross disciplinary. Peak and volume of river flows are functions of the catchment surface characteristics. This means that any impacts to the run-off regime (for example surface sealing or river training) could affect people and land users in the lower catchment. Thus, upstream activities can cause higher flood peaks, and also entail higher damages downstream. These damages are either borne by the affected parties or they are mitigated by state financed flood defence works or offset with financial compensation. These costs are usually not included in the economic considerations of the upstream land user who is partially causing them. In economic terms, these effects are referred to as unidirectional externalities. This means that a producer can export parts of his production costs to third parties and these are not included in the price of the product. The Herzogbach is a small tributary of the Danube River in Lower Bavaria. It is located in a rural area, dominated by intensive farming practices. Two villages (Bachling and Buchhofen) in the headwaters and middle section of the catchment and one city (Osterhofen) in the lower catchment were analysed to determine the impact of upstream land use practices on the flood situation. A combination of hydrological and hydraulic modelling provided the core data to allow the interpretation of economic data, using methods of cost damage estimation. A hydrological model of the catchment provided hydrograph simulations based on (a) a regionalisation approach, (b) hydrologic flood routing and (c) hydrologic reservoir routing. A two dimensional stream flow model was then used to convert the hydrographs into flood levels, to simulate the run-off in settled areas and determine the flood affected areas, flood levels and flow velocities. Estimates for flood damages or mitigation costs resulting from different hydrological scenarios were compared. The scenarios are based on different land uses and allow economic externalities to be estimated. It was found that intensive farming and river training increase the peaks, shape and volume of flood waves in comparison to extensive land use, grassland or forest. In the study area, especially river training reduced the detention effect of the river bed and the natural flood plain. These significant changes to the natural run-off regime directly affect land use in the lower catchment through flood damages and increased flood risk, and by reducing the effectiveness of planned or existing flood protection works. The thesis concludes with linked technical and economic findings which indicate a rich potential new area for research - “hydroeconomics”. The published literature shows few people have worked in this cross disciplinary area. The technical finding is that changes to land use, especially in agriculture, can increase the flood damages in downstream settlements or increase the cost of flood mitigation works significantly. From an economic point of view, this is a unidirectional externality which should be considered in catchment and flood management. Possible solutions could include the control of land use and instruments such as separate waste water fees for rainwater and sewage or run-off certificates.

Peak and volume of river flows are functions of the catchment surface characteristics. This means that any impacts to the run-off regime (for example surface sealing and river training) could affect people and land users in the lower system. The costs of flood defence or compensation of damages are usually not included in the economic calculation of the upstream land owner or land user. In economic terms these effects are referred to as unidirectional externalities. This paper presents a methodology to identify externalities related to land use and run-off and describes the relevant cause-effect relations and how they can be modelled. The Herzogbach is a small tributary of the Danube River in Lower Bavaria. It is located in a rural area, dominated by intensive farming practices. A combination of hydrological and hydraulic modelling provided the core of the project methodology to allow the interpretation of economic data. Comparisons of damage estimates resulting from different hydrological scenarios based on different land uses, and flood mitigation costs were used to show the economic significance of human impacts.

Development of flood risk in mountain catchments and related perception, vol. 9

In: Geophysical Research Abstracts

  • 2007
The RISKCATCH project aims to deliver new, practical and viable solutions for anintegrated risk-assessment-based management of natural hazards in Alpine environments and related forelands. A special focus is on the interaction of technical and non-technical measures during recent flood events in catchment areas. Comparing the status quo and historical development of risk and forecasting possible future developments based on scenarios, necessary action will be derived and efficiency of non-technical measures of flood defence will be evaluated. Based on the assessment of historical and possible future development of hazard, values at risk and vulnerability, non-technical measures will be evaluatedfrom an economic and technical point of view using scenario technique, cost-benefit analysis and cost comparison method. With respect to different scenarios of the temporal development of risk, maps will be generated and assessed with respect to its perception, using the method of graphic semiology. Graphic semiology is an innovative tool to evaluate such information, and is based on thestatistical analysis of eye movements of test persons exposed to visual information.

Are floods in part a form of land use externality, vol. 9

In: Geophysical Research Abstracts

  • 2007
Peak and volume of river flows are functions ofthe catchment surface characteristics. This means that anyimpacts to the run-off regime (for example surface sealingand river training) could affect people and land users in thelower system. The costs of flood defence or compensationof damages are usually not included in the economic calcu-lation of the upstream land owner or land user. In economicterms these effects are referred to as unidirectional externali-ties. This paper presents a methodology to identify externali-ties related to land use and run-off and describes the relevantcause-effect relations and how they can be modelled. TheHerzogbach is a small tributary of the Danube River in LowerBavaria. It is located in a rural area, dominated by intensivefarming practices. A combination of hydrological and hy-draulic modelling provided the core of the project methodol-ogy to allow the interpretation of economic data. Compar-isons of damage estimates resulting from different hydrolog-ical scenarios based on different land uses, and flood miti-gation costs were used to show the economic significance ofhuman impacts.

Lower Bavaria is part of the free state Bavaria an located at the border of Germany to Austria. Lower Bavaria has an area of 10330 km² and 1,2 Mio. inhabitants. The land use in Lower Bavaria is marked by agriculture with a part of 52%. The high importance of the agricultural use in Lower Bavaria leads to some very serious problems concerning mostly soil and water. For example, problems concerning soil are erosion and contamination by agricultural sprays, which results in risk for the near streams and rivers in addition to the risk for the ground water. On the one hand this means decreasing productivity for agricultur e because of the removal of the uppermost fertility soil layer, and on the other hand the consequences concerning water quality.
