This study presents a framework for regional smart energy planning for the optimal location and sizing of small hybrid systems. By using an optimization model – in combination with weather data – various local energy systems are simulated using the Calliope and PyPSA energy system simulation tools. The optimization and simulation models are fed with GIS data from different volunteered geographic information projects, including OpenStreetMap. These allow automatic allocation of specific demand profiles to diverse OpenStreetMap building categories. Moreover, based on the characteristics of the OpenStreetMap data, a set of possible distributed energy resources, including renewables and fossil-fueled generators, is defined for each building category. The optimization model can be applied for a set of scenarios based on different assumptions on electricity prices and technologies. Moreover, to assess the impact of the scenarios on the current distribution infrastructure, a simulation model of the low- and medium-voltage network is conducted. Finally, to facilitate their dissemination, the results of the simulation are stored in a PostgreSQL database, before they are delivered by a RESTful Laravel Server and displayed in an angular web application.

Prioritizing the Chicken or Egg? Electric Vehicle Purchase and Charging Infrastructure Subsidies in Germany
Politics and Governance, vol. 8, no. 3, pp. 185-198
2020
DOI: 10.17645/pag.v8i3.3025
Abstract anzeigen
To meet current targets for greenhouse gas emissions in Europe, emissions, especially those originating from the road transport sector, need to be reduced. Plans are to achieve this goal by substituting fossil fuel vehicles with electric vehicles (EVs). This article first discusses conceptually the impact of an increasing share of EVs on the electricity grid and suitable locations for charging stations with examples from a Case Study in Lower Bavaria. Secondly, the impact of purchase subsidies on EV purchases in Germany, a high-income country characterized by an important automotive industry and an increasing share of private vehicles is examined. To achieve this, yearly information on EV purchases were analyzed by applying the Synthetic Control Method. Combining data from different sources including the European Alternative Fuels Observatory, Eurostat, and the European Automobile Manufacturers' Association, an overall picture was developed. Results indicate a difference between private, semi-public, and public charging infrastructures. Its spatial distribution does not correspond to a specific development strategy. Moreover, EV subsidies have a limited effect in Germany when controlling for market size. Limiting the discussion to a trade-off between subsidizing infrastructures or EV purchases obviates the multidimensionality of the problem as neither of them may be sufficient to accelerate the transition per se. Furthermore, if electricity provided for EVs comes mainly from fossil carriers, the changes in the road transport sector will not yield the expected emission reductions. The transition towards renewables is directly intertwined with the effects of EVs on emission reductions in the road transport sector.

3D Mapping to collect volunteered geographic information
Proceedings of the 2020 10th International Conference on Advanced Computer Information Technologies (ACIT) [September 6-8, 2020; Deggendorf]
2020
DOI: 10.1109/ACIT49673.2020.9208958
Abstract anzeigen
This paper discusses the concept of crowdsourcing in combination with our new developed 3D viewer which is integrated in the technical infrastructure of PUBinPLAN, our digital participation platform. The voluntarily gathered information is collected on PUBinPLAN, where people can join and share their spatial knowledge on our 3D models of the city of Deggendorf and the Deggendorf Institute of Technology. Firstly, the technical details of the 3D viewer and the implementation into the PUBinPLAN website are explained and then, in a case study, the performance on different devices and in different browsers is analysed to ensure a smooth mapping experience for architectural approaches. This creates an added value to participatory regional and spatial planning processes.

Kommunale Homepages zur nachhaltigen Bürgerkommunikation und -partizipation – ein Vergleich von Stadt und Land
Bavarian Journal of Applied Sciences, vol. 5, no. 1, pp. 412-422
2019
Abstract anzeigen
Motiviert durch die aktuellen Trends in der digitalen Kommunikation hin zu
interaktiven Homepages und Sozialen Medien, thematisiert dieser Beitrag das
quantitative Angebot von digitalen Funktionen auf kommunalen Homepages
im Vergleich von Stadt und Land. Dazu findet eine Sichtung von insgesamt 209
Homepages von Kommunen in Bayern mit unterschiedlicher Einwohnergröße und
unterschiedlicher infrastruktureller Ausgangslage statt. Die Analyse unterscheidet
dabei in die etablierten Bereiche des (1) Bürgerkontakts (Web 1.0) sowie in (2)
Bürgerdialog und (3) Soziale Medien mit interaktiven und Web 2.0-Angeboten.
Die Ergebnisse zeigen, dass ländliche Kommunen in den beiden ersten Kategorien
mit den städtischen Kommunen auf Augenhöhe agieren, beim Einsatz Sozialer
Medien aber bisher weit zurückbleiben. Gründe hierfür können sowohl mangelnde
Kompetenzen im Umgang mit Sozialen Medien als auch die infrastrukturelle,
personelle und finanzielle Ausstattung der Kommune sein. Dennoch bedarf es
künftig einer proaktiven Herangehensweise der Kommunen, um diese Lücke zu
schließen und moderne digitale Kommunikationsangebote im ländlichen Raum weiter zu stärken.
Recent trends show the development from digital communication to interactive
homepages and social media features. This contribution discusses the quantifiable offer
of digital features on urban and rural municipal homepages in comparison. For this,
209 homepages of Bavarian municipalities with differences concerning population and
infrastructural situation were analyzed. The analysis discerns three sections: (1) contact
with citizens (web 1.0), (2) dialogue with inhabitants and (3) social media and interactive
web 2.0 features. The results show that urban and rural municipalities are head to head
in the first two categories, in the third case, however, the rural areas are left far behind.
Reasons for this might be the lack of competences in using social media and the lack of
infrastructural, personal and financial resources. It is necessary to actively tackle this
issue in order to close this gap and to strengthen contemporary communication in rural
areas.

Abstract anzeigen
The effects of digitization on social coexistence have been a subject of controversynot only since the increased use of social media for political campaigns. Digital platforms are also being developed which,from the perspective of spatial planning and geography,enhancecommunication between administrations and citizens at the local municipal level. These applications are being developedin relation to three areas:(1)the everyday experiences and competences of citizens in dealing with geomedia, especially the use of smartphones; (2)the individual process design for a particularparticipatory case; (3)the desired societal or local political benefit. This paperdeals with these three aspects and discusses five selected examples of how digital participation platforms can be designed to include the use of geomedia. Based on experiences with the proprietary development of the web application PUBinPLAN in particular and on itscomparisonwith other platforms, insights can be derived with regard to success factors as well as to opportunities and risks

This paper discusses the impact of ICT for creating sustainable rural regions. An empirical analysis of 255 Bavarian communes in 2018 showed, that there is a lack of digital content on the communes' homepages. New ideas are needed for participation and communication in rural communes. To close this gap, PUB in PLAN, a digital participation platform was initiated. This platform is the basement for new, smart and effective participation projects using digital and analog forms of moderation for sustainable and intelligent city developments.

Electric Charging Demand Location Model—A User- and Destination-Based Locating Approach for Electric Vehicle Charging Stations
Sustainability, vol. 11, no. 8
2019
DOI: 10.3390/su11082301
Abstract anzeigen
In recent years, with the increased focus on climate protection, electric vehicles (EVs) have become a relevant alternative to conventional motorized vehicles. Even though the market share of EVs is still comparatively low, there are ongoing considerations for integrating EVs in transportation systems. Along with pushing EV sales numbers, the installation of charging infrastructure is necessary. This paper presents a user- and destination-based approach for locating charging stations (CSs) for EVs—the electric charging demand location (ECDL) model. With regard to the daily activities of potential EV users, potential positions for CSs are derived on a micro-location level in public and semipublic spaces using geographic information systems (GIS). Depending on the vehicle users’ dwell times and visiting frequencies at potential points of interest (POIs), the charging demand at such locations is calculated. The model is mainly based on a survey analyzing the average time spent per daily activity, regional data about driver and vehicle ownership numbers, and the georeferenced localization of regularly visited POIs. Optimal sites for parking and charging EVs within the POIs neighborhood are selected based on walking distance calculations, including spatial neighborhood effects, such as the density of POIs. In a case study in southeastern Germany, the model identifies concrete places with the highest overall demand for CSs, resulting in an extensive coverage of the electric energy demand while considering as many destinations within the acceptable walking distance threshold as possible.

Extracting Relevant Points of Interest from Open Street Map to Support E-Mobility Infrastructure Models
Bavarian Journal of Applied Sciences, vol. 4, no. 1, pp. 323-341

Abstract anzeigen
Neben kommerziell bereitgestellten Geodaten nehmen freiwillig erhobene geographische Daten (VGI, volunteered geographic information) in der Forschung einen wachsenden Stellenwert ein. Plattformen wie OpenStreetMap (OSM) bieten inzwischen eine enorme Menge an Geodaten, deren Qualität und deren Mehrwert für die Forschung zunehmend kritisch betrachtet werden. Besonders dann, wenn es um räumliche Planung geht, müssen die Daten vor der Anwendung angemessen validiert und bereinigt werden. In diesem Artikel wird ein Datenverarbeitungsmodell vorgestellt, mit dem OSM-Daten so
aufbereitet werden können, dass der Bedarf an Ladeinfrastruktur für Elektroautos über von Nutzern eingetragene Point of Interests (POI) räumlich möglichst genau erfasst und abgebildet werden kann. Zunächst erfolgt eine Selektion relevanter Datensets durch eine Prävalidierung. Im zweiten Schritt werden die wichtigsten POI selektiert und spezifiziert. In einem dritten Schritt werden alle OSM-immanenten Schwierigkeiten beseitigt. Das hier vorgestellte Datenverarbeitungsmodell ist auf das Thema Elektromobilität zugeschnitten, für welches POIs in die vier Zeitkategorien Arbeit, Leben, Einkaufen und Freizeit eingeteilt werden, um so den Bedarf an Ladeinfrastruktur zu erheben. Durch dieses Modell der Datenverarbeitung soll die Energienachfrage für Elektroautos räumlich möglichst realistisch dargestellt werden und Rohdaten mit ihren bekannten Fehlern durch den OSM-Datensammlungsprozess bereinigt aufbereitet werden. Anhand einer Fallstudie, die im bayerisch-tschechischen Grenzraum durchgeführt wurde, wird gezeigt, dass die Fehlerrate durch die Implementierung validierter Daten um ca 10% reduziert werden kann.
