摘要：
The wake effect will lead to different frequency regulation capabilities of wind turbines in the same wind farm. In order to make full use of the frequency regulation capability of each wind turbine in a wind farm to improve the system frequency performance，a frequency collaborative support control of wind farm considering operation state difference of wind turbines is proposed. The proposed control strategy is divided into two stages. In the frequency support stage，the leaderless consistency algorithm is used to exchange the state information between the wind turbine and its neighboring wind turbine in real time to achieve reasonable power distribution，and on this basis，the frequency regulation coefficient is adjusted adaptively to ensure the safe operation of the wind farm. When the wind turbine switches from the frequency support stage to the rotor speed restoration stage，the progressive rotor speed restoration control is adopted to realize the smooth transition between the two controls and alleviate the second frequency drop problem. The simulation analysis of the four-machine two-area system and the three-terminal four-area system with wind farms is carried out. The simulative results verify that the up and downward frequency regulation control effect of the proposed control strategy is superior to that of the centralized control. © 2024 Electric Power Automation Equipment Press.
