Optimal Frequency Controller Parameters of Wind Turbines Participating System Frequency Control

Control of variable speed wind turbines to participate system frequency control has become a new requirement for wind turbines in a high penetrated wind farm power system. This paper focuses on selection of the frequency controller parameters of the wind turbines to improve the frequency control effect. Frequency control method of the wind turbines is presented in this paper. Considering the system frequency response, the synthetic frequency response model is built, a multi-objective function of evaluating the effect of system frequency response is proposed, then genetic algorithm is used to determine the optimal frequency controller parameters. The performance of the frequency control effect with optimal frequency controller parameters of the wind turbines is validated in Matlab/Simulink.
