Study on automatic generation control strategy for wind farm

Aiming to suppress the frequent fluctuation of large-scale power system with wind farm,this paper proposes to let wind farm participate in the frequency control of large-scale electric power system by fuzzy control,which means to modulate the frequency of power system by utilizing the change of wind farm compensation short-term load in order to modulate the change of system active power brought by the randomicity of load change and wind farm contribution.The simulated calculation proves that the method is able to reduce frequency fluctuation of power system.
