Energy Yield and Power Fluctuation of Different Control Methods for Wind Energy Converters

With worldwide increasing shares of electricity generated by wind energy converters, their influence on the mains stability and their reliable energy contribution becomes more and more relevant. The system management of wind energy converters has great influence on the power yield and the damping/amplification of wind caused power fluctuations. This paper compares the performance of different control methods for wind energy converters, regarding their energy yield and electrical power output fluctuation at different wind conditions. The results show that the Stochastic Dynamic Optimization control combines very high energy yield with the best fluctuation damping.
