Kurzbeschreibung (Abstract)
In this work, a method is presented to ensure more regional use of the generated electric power in neighboring medium voltage grids, thus increasing their capacity to host renewable energy sources. The method consists of a grid topology optimization during operation, where load segments between two neighboring medium voltage grids are switched over. The considered grids should have different load and generation characteristics as well as an existing coupling possibility between them. The results of this concept applied to two real medium voltage grids in a southwestern region in Germany show that the yearly fed-up energy to the high voltage grid could be reduced by up to 19 %. In addition, a guaranteed free hosting capacity could be added to a grid depending on the base load of the switchable segment. It is also shown that loop-flow currents can occur during switching and can be critical to the grid if not well calculated.
