Technical constraints on and efficient strategies for the integration of wind energy
Based on simulations of the German and Austrian electricity systems, the impacts of wind generation on power plant operation are analysed. Accurate forecasts play the major role when integrating wind power because they determine additional reserve capacity as well as any additional imbalance. Additional balancing power can be limited to less than 10 % of the installed wind capacity if improved forecast tools or shorter forecast horizons are used. Additional balancing costs are below 5 EUR per MWh wind energy depending on the forecast accuracy and the available balancing capacity. Balancing markets need developments which improve the accessibility for demand-side options as simulations have shown potential cost reductions of 25 %.
