Power Grid Resilience: Short-term Fluctuations and Intermittency — •Hauke Haehne, Matthias Waechter, and Joachim Peinke — Carl von Ossietzky University Oldenburg, Institute of Physics and ForWind, 26111 Oldenburg, Germany
Future power grids will be fed by a high share of renewable generation with strongly intermittent fluctuation patterns of produced power. This poses new challenges for resilient grid operation. From a physical perspective, the frequency of the alternating current in a power grid provides information on the instantaneous ratio of demand to production. We use high-resolution frequency measurements of the continental European power grid to analyze resilience regimes of the electric transport and actor system. We characterize fluctuations on different time scales and compare our findings to prior results from renewable power systems analysis. We combine stochastic methods and network dynamics, data analysis and simulations.
