Description
Summary:The integration of fluctuating power generation based on renewable energy systems (RES-E) in distribution grids require grid reinforcement resulting from high feed-in peaks. Introducing storage assets can decrease these peaks. For this, storage technologies need to be chosen and dimensioned according to the prevailing RES-E portfolio. In this paper characteristic parameters for storage devices, which are used for peak reductions of photovoltaic and wind generation, are derived. For this, real world data of generators located in a German distribution grid are used. An empirical relation between the peak to be reduced and the required capacity and the number of charging cycles is given enabling a discussion and choice of appropriate storage technologies. The achieved results show, that the parameters of the storage are influenced not only by the considered RES-E technology but also by the number of decentralized generators.
