Analysis and optimization of power grid stability for rising feed-in of wind energy — •Jean-Luc Schnipper and Philipp Maass — Universität Osnabrück, Institut für Physik, Germany

On the basis of the swing equations for power flow in electricity grids and heterogeneous test grid structures, we analyse the impact of wind-power feed on grid stability. The stability is quantified by the exceedance, that is the fraction of time the network frequency exceeds thresholds triggering primary control measures. Wind farms are incorporated into test grids by replacing conventional generators. They are represented by stochastically driven single turbines with mean power output equal to that of the replaced conventional generator. We find that that the exceedance per unit of installed wind power can vary substantially depending on which generators are substituted and to which extent wind fluctuations are correlated at different locations of wind power injection. This offers strategies for maintaining best power grid stability by optimized spatial allocation of wind farms.
