The invention relates to a wind power access system energy storage charging and discharging control method considering the voltage stability, which aims to improve the overall voltage stability of a wind power access system according to real-time network information of the system and the predicted output condition of a wind power plant, determines the working state of an energy storage device andfurther formulates a charging/discharging scheme of the energy storage device. The method comprises the steps of S1, determining a typical wind power output scene by using a wind power predicted value; S2, taking the minimum overall voltage stability index of the wind power access system as an objective function, and determining a constraint condition so as to establish an energy storage chargingand discharging control model; and S3, solving the energy storage charging and discharging control model by using the quantum particle swarm so as to obtain a charging and discharging scheme of the energy storage device in each time period. The method not only is simple and rapid, but also can fully play the role of the energy storage device and improve the voltage stability of the system.
