Impact of intermittent power fluctuations on the dynamics of power grids — Katrin Schmietendorf1, Joachim Peinke1, and •Oliver Kamps2 — 1ForWind - 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.
