The impact of increased shares in variable renewable energy sources on the power system is subject to a controversial public debate. The question to what extent grid stability is influenced, especially the effect on distribution grids, is not well-understood but has come into focus, recently.
Thus, we investigated the influence of intermittent fluctuations from renewables on frequency stability with respect to network topology. Here, single node fluctuations are exerted onto each node of a typical distribution grid and the reaction in network frequency is quantified studying the frequency tail distributions.
We chose two prominent model cases which stand for today's Mid-Voltage distribution and potential future micro grids. Results and potential balancing measures as decentral smart grid control with the help from electric vehicles will be discussed.
