Abstract: Aiming at the problem of differences in the frequency regulation capabilities of wind farms operating under different wind conditions, a coordinated frequency regulation power allocation strategy in which multiple wind farms participate in primary frequency regulation of the power grid is proposed, and the frequency regulation capability evaluation method of wind farms is improved. A wind farm frequency modulation power collaborative control method is proposed, which is based on the primary frequency modulation control strategy of each wind turbine unit in the wind farm using inertia control and droop control. The aim is to allocate frequency modulation power according to the capacity of the wind farm rotor kinetic energy, thereby effectively improving the frequency modulation power response characteristics of the wind farm during the frequency support process. Through simulation analysis, the improved wind farm frequency modulation capacity evaluation method can effectively evaluate the frequency modulation capacity of wind farms operating under different wind conditions. Using the improved cooperative control strategy of wind farms, the frequency modulation power between wind farms can be allocated according to capacity, and the frequency modulation power can be fully utilized, and the frequency response of the system is significantly improved compared with the traditional cooperative control.
