As the penetration rate of new energy in the power system continues to increase,the large-scale grid connection of wind power is one of the important factors affecting the stable frequency operation of the power system. Configuring energy storage can provide transient frequency support for the system,improve wind power fluctuations,and enhance the stability of wind power generation. Firstly,by considering the primary frequency regulation requirements of wind farms and starting from the operating status of batteries,a state of charge (SOC)control strategy taking into account charge coefficient and discharge states was proposed,and a battery service life model was established. On this basis,with the overall goal of minimum sum of annual comprehensive costs of wind storage systems,a power and capacity optimization configuration model for energy storage systems was constructed that taken into account the state of charge and battery life. Secondly,the ant lion algorithm was used to solve the optimization results,and the effect of complex cost,battery life,and charge status on the optimization result was analyzed. Finally,the effectiveness of the results through simulation was validated.
