The embodiments of the invention provide an active power and reactive voltage control method and device of a wind-storage combined power generation system, wherein the method comprises the steps of: obtaining the active power and reactive voltage of an energy storage power station in real time; according to the deviation of the active power and the deviation of the reactive voltage, determining the priority of adjustment carried out on an active power instruction and a reactive voltage instruction; and according to the determined priority, adjusting the active power instruction and the reactive voltage instruction. According to the scheme, the active power and the reactive voltage of the energy storage power station are coordinated and corrected according to the priority. 本发明实施例提供了种风储联合发电系统有功功率和无功电压的控制方法及装置，其中，该方法包括：实时获取储能电站的有功功率和无功电压；根据有功功率的偏差和无功电压的偏差，确定对有功功率指令和无功电压指令进行调整的优先级；根据确定的优先级，对有功功率指令和无功电压指令进行调整。该方案可实现根据紧迫程度对储能电站的有功功率和无功电压进行协调修正。
