The annual conference “Future Electricity Grids” took place this year in virtual format from January 27-28, 2021, and February 3-4, 2021. The FfE was represented at the conference with three scientific contributions on current research questions in the topic area “Design of future-capable grid infrastructures”. At the poster session, Andreas Weiß, Simon Köppl, and Daniela Wohlschlager presented the results of the following contributions:
Simulative analysis of future grid load – the interaction of PV and electromobility in the urban distribution grid
Andreas Weiß, Adrian Ostermann, Valerie Ziemsky
As part of the joint project München elektrisiert (Munich electrified), the current and future grid load in the urban distribution grid of the city of Munich is being simulatively determined, with the development of electromobility being the focus of the investigations. In the published case study, the focus is primarily on the simulation and evaluation of the interaction of PV systems and electromobility in the future urban distribution grid. In scenarios, electromobility developments in combination with possible PV additions are considered and evaluated. The results illustrate that despite a higher share of PV power and a larger number of electric vehicles in the region’s medium distribution grid, no operating resource overload occurs. Also, changing the charging strategy of electric vehicles at buildings with PV installation to self-consumption optimized charging does not lead to any significant change in grid load or restriction of vehicles.
Altdorf Flexmarkt – Findings after Four Years of SINTEG – Decentralized Flexibility for Grid Congestion Management in Real Operation
Simon Köppl, Thomas Estermann, Elisabeth Springmann, Andreas Zeiselmair
The paper covers the most important results from the C/sells project around the Altdorf Flex Market (ALF). It presents lessons learned in the area of process enhancement and optimization, the application of the iMSys infrastructure, and the design of a tool for market-based congestion management in the distribution grid.
Participative Aspects in the Intelligent Energy System – Between Theory and Practice
Daniela Wohlschlager, Thomas Estermann, Simon Köppl
Dietmar Miller, Fabian Holl (Smart Grids-Plattform Baden-Württemberg e.V)
The article covers findings on citizen involvement in demonstration projects using the example of the methodological approach and practical implementation in the ALF field trial. Results of an investigation of aspects of citizen participation in the context of smart solution concepts are presented collected through a comparative analysis of different demonstration projects. Finally, the paper presents general recommendations for future solution concepts with participatory aspects based on lessons learned from various C/sells project activities.
