This research paper aims to analyze the competition effects of CES with simultaneous application of DR. The optimization results of the synthetic case studies provide insights in the profitability level, the service provision and the flexibility potential. While even under requested legal circumstances a CES is only partially profitable, the economic situation improves in terms of an optimal storage utilization.

Until now, generated electricity of decentralized systems is to the largest extent only used by the property owner directly or fed into the public grid. To make better use of the generated electricity, it is necessary to find business models that provide an opportunity for different market actors, such as municipal utilities and residential prosumers. Due to the importance, yet low-anticipated monetary potential of such solutions, the legislator encourages their implementation by exemption of statutory fees, levies and taxes as well as by offering public remunerations, premiums and compensations in some cases. Capitalizing on these benefits, however, is only feasible under compliance with the legal requirements. In the light of the considerations above, this work states and analyzes the legal and regulatory framework of different business models within the German energy landscape. The major aim is to identify opportunities and challenges for the implementation of the business models self consumption, direct consumption, direct marketing, demand response, community electricity storage and net metering at the municipal level. The findings show that the profitability of various decentralized on-site business models depends primarily on the current statutory cost exemptions and compensations. At the same time, the regulation is characterized by unsystematic specific exemptions which leads to uncertainty regarding long-term planning. Additionally, although not directly privileged by the existing legal framework, municipal utilities are better suited to handle the legal burdens due to their experience and their administrative infrastructure.}, language = {en} } @incollection{SchellerJohanningBruckner, author = {Scheller, Fabian and Johanning, Simon and Bruckner, Thomas}, title = {Integrierte techno-sozio-{\"o}konomische Modellierung urbaner Systeme}, series = {Agentenbasierte Modellierung urbaner Transformationsprozesse}, booktitle = {Agentenbasierte Modellierung urbaner Transformationsprozesse}, editor = {Johanning, Simon and Scheller, Fabian and K{\"u}hne, Stefan and Bruckner, Thomas}, isbn = {9783832554132}, doi = {10.30819/5413.01}, pages = {7 -- 17}, language = {de} } @inproceedings{SchellerReicheltDienstetal., author = {Scheller, Fabian and Reichelt, David G. and Dienst, Steffen and Johanning, Simon and Reichardt, Soren and Bruckner, Thomas}, title = {Effects of implementing decentralized business models at a neighborhood energy system level: A model based cross-sectoral analysis}, series = {14th International Conference on the European Energy Market (EEM)}, booktitle = {14th International Conference on the European Energy Market (EEM)}, isbn = {978-1-5090-5499-2}, doi = {10.1109/eem.2017.7981910}, pages = {1 -- 6}, abstract = {The reliable integration of decentralized energy technologies and the associated system transformations represent a challenging task.

This paper explores stakeholder influences on residential photovoltaic adoption from a procedural perspective, so-called stakeholder dynamics. The major objective is the understanding of underlying mechanisms to better exploit the potential for residential photovoltaic uptake. Four focus groups have been conducted in close collaboration with the independent institute for social science research SINUS Markt- und Sozialforschung in East Germany. By applying a qualitative content analysis, major influence dynamics within three decision stages are synthesized with the help of egocentric network maps from the perspective of residential decision-makers. Results indicate that actors closest in terms of emotional and spatial proximity such as members of the social network represent the major influence on residential PV decision-making throughout the stages. Furthermore, decision-makers with a higher level of knowledge are more likely to move on to the subsequent stage. A shift from passive exposure to proactive search takes place through the process, but this shift is less pronounced among risk-averse decision-makers who continuously request proactive influences. The discussions revealed largely unexploited potential regarding the stakeholders local utilities and local governments who are perceived as independent, trustworthy and credible stakeholders. Public stakeholders must fulfill their responsibility in achieving climate goals by advising, assisting, and financing services for low-carbon technology adoption at the local level.

The residential photovoltaic diffusion model PVact features numerous stochastic influences that prevent straightforward optimization-driven calibration.From the analysis of the results of a case-study on the cities Dresden and Leipzig (Germany) based on three error metrics (mean average error, root mean square error and cumulative average error), this research identifies a parameter range where stochastic fluctuations exceed differences between results of different parameterization and a minimization-based calibration approach fails.Based on this observation, an approach is developed that aggregates model behavior across multiple simulation runs and parameter combinations to compare results between scenarios representing different future developments or policy interventions of interest.}, language = {en} } @article{JohanningSchellerAbitzetal., author = {Johanning, Simon and Scheller, Fabian and Abitz, Daniel and Wehner, Claudius and Bruckner, Thomas}, title = {A modular multi-agent framework for innovation diffusion in changing business environments: conceptualization, formalization and implementation}, series = {Complex Adaptive Systems Modeling}, volume = {8}, journal = {Complex Adaptive Systems Modeling}, number = {1}, doi = {10.1186/s40294-020-00074-6}, abstract = {Understanding how innovations are accepted in a dynamic and complex market environment is a crucial factor for competitive advantage.

To address this gap, we developed an agent-based residential rooftop photovoltaic adoption model called PVact. Our model analyzes the interactions of potential household adopters based on their utility functions and social network, with a focus on the role of monetary evaluation and social pressure in adoption behavior. In this paper, we aim to assess the influence of monetary evaluation and social pressure in an abstract case study based on real-world data from the municipality of Leipzig, Germany. We consider stochastic dynamics through scenario analysis to investigate the influence of these factors on adoption behavior. Our results show that monetary evaluation and social pressure have a significant impact on adoption behavior. Specifically, we find shifting adoption patterns with an increased requirement for monetary returns and higher level of normative pressure required for households to act. Higher resistance against these pressure shows more stochastic variations, more pronounced tipping points and stronger run-away effects.}, language = {en} }
