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

With worldwide increasing shares of electricity generated by wind energy converters (WECs), their influence on the mains stability and contribution to reliable energy supply becomes more and more relevant. The system management of WECs 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 WECs, 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 highest damping of fluctuations.
