The low-voltage grid of the real laboratory can be interconnected into four grid types: rural, village, suburban and urban. In these, prosumers are examined in various expansion scenarios and their impact on grid operation to discuss the central questions of the research project.
The basis for the future scenarios is the federal government's Easter 2022 package and the resulting draft legislation. Here, specific expansion targets for renewable energies are defined. The energy policy goals defined by the federal government are staggered and affect the entire energy sector. The examinations in the lab focus on the scenario years 2020, 2030 and 2045. In the scenarios, various prosumer structures in the private household sector in Hesse are mapped. In addition, a fourth scenario, full expansion, is developed. This describes the maximum prosumer expansion, in which all buildings have a PV system, battery storage, an electric heat pump and a private charging station for electric cars.
