Abstract
This report seeks to investigate how the spatial distribution of wind turbines affect the required flexibility in the future German electricity system. The research question is answered in four steps by utilizing a geo information system and an Excel model. First, the available areas on which wind turbines can be placed, without interfering with other interests, are determined. Second, two wind turbine distribution scenarios, the best wind site scenario and the even distribution scenario, are determined. Third, the production profiles of the two scenarios are calculated, considering two different wind turbine types and 70 wind profiles from all over Germany. Fourth, the residual loads of both scenarios are calculated and the required flexibility of the electrical system is analysed according to the capacity and characteristic. It is found, that the effect of the higher installed capacity, in the even distribution scenario, surpasses the smoothing effect of the distributed wind turbine placement. Further, the residual load curve of the even distribution scenario is smoother, which results in lower flexibility gradients but the same required flexibility capacity.
