Impact of intermittent power fluctuations on the dynamics of power gridsKatrin Schmietendorf1, Joachim Peinke1, and •Oliver Kamps21ForWind - Center for Wind Energy Research, Institute of Physics, University of Oldenburg, Germany — 2Center for Nonlinear Science, University of Münster

The increasing share of fluctuating energy sources like wind energy poses big challenges for the stability of power grids and the resilience of energy supply systems in general. From the physics point of view the phase and voltage dynamics of a power grid can be described by a Kuramoto-like model of coupled oscillators [1]. To investigate the influence of wind energy production, which is known to exhibit strongly non-Gaussian statistics [2], on the phase and voltage stability we use a Langevin type model mimicking the main features of wind power time series. We compare our findings with results obtained for Gaussian noise and real power time series.
