Impact of Wind Feed-in on Power System Stability and Quality — •Katrin Schmietendorf1, Joachim Peinke1, and Oliver Kamps2 — 1Universität Oldenburg, ForWind — 2Universität Münster, Center for Nonlinear Science
Feed-in fluctuations are one of the major challenges for future electrical power grids. Short-term fluctuations on the second and sub-second scale are not counteracted by standard load balancing mechanisms. Moreover, on these time scales feed-in fluctuations are strongly non-Gaussian with intermittent increment statistics. We focus on short-term wind power fluctuations with realistic properties: temporal correlation, power spectrum, and intermittent increments. We discuss the implications on power system stability in terms of noise-induced desynchronization. Furthermore, we show that the turbulent nature of wind significantly reduces power quality as it is directly transferred into the fluctuations of frequency and voltage.
