The invention relates to an active-reactive coordination control method and system for a wind and light storage station. The method comprises the following steps: acquiring a real-time value of operation data of the wind and light storage station and a target value issued by a dispatching center; two control modes are designed for the integration characteristic of the combined power station, and an active power priority or reactive power priority control strategy is executed according to the control modes and the operation state. Based on different control strategies, a multi-target optimization model considering active power loss, node voltage deviation, active power and reactive power deviation and active power regulation cost reduction is established, active and reactive power coordination control of the combined power station can be realized, power and voltage distribution in the station can be optimized, and the operation economy, safety and stability of the system can be effectively improved. 本发明涉及一种风光储
