The invention relates to a method for generating a switching plan of a capacitor bank of a wind power transmission system through a flexible direct current power network, belonging to the technical field of voltage control of a power system. The invention provides a method for generating a switching plan of a capacitor bank of a wind power transmission system through a flexible direct current network, which takes into account the regulating characteristics of the capacitor bank. According to the wind power forecast information, the capacitor bank switching plan is generated by two-stage robustoptimization. The static reactive power of the capacitor bank is utilized to maximize the reactive power replacement, and the dynamic reactive power reserve of the system is increased. The capacitorbank switching plan generated by the method has the optimality under the worst wind power scenario, and reduces the reactive power capacity requirement of the flexible DC converter station under the wind power uncertainty, thereby enabling the flexible DC converter station to have more capacity to receive wind power; The method can make full use of the static reactive power regulating ability of the capacitor bank to carry out reactive power replacement and increase the dynamic reactive power reserve of the system.
