A coordinated control strategy for wind farm primary frequency regulation timing was proposed to address the issue of secondary frequency drop during wind farm frequency regulation.Firstly,a quantitative analysis was conducted on the relationship between wind turbine frequency response time,speed recovery time,and frequency regulation power under different wind speeds.Based on it,a wind farm primary frequency regulation timing coordination control model was constructed,and a wind farm primary frequency regulation control strategy was put forward to avoid secondary frequency drop.The simulation results show that the proposed wind farm primary frequency regulation timing coordination strategy not only fully utilizes the frequency regulation ability of each wind turbine,but also effectively avoids the secondary frequency drop of the whole system,which is conducive to the safe and stable operation of the system.
