Abstract：When battery storage stations participating in power system transient stability emergency control, the battery charge-discharge frequency is very high, so the long-time operation will shorten the battery working life. It could be found that the actual working time of the energy storage station in the process of transient stability control is very short by extensive simulation. Therefore, it is necessary to calculate its optimal working time. In this paper, the battery energy storage transient model was established. The damping torque method was used to analyze the mechanism of improving the stability of power grid by energy storage station. Meanwhile, the influence of its different capacity configurations and different connecting positions was expounded. The data of rotor speed, power angle, electromagnetic power and mechanical power of the generator were collected on-line in time. Based on the extended equal area criteria,the optimal working time of the energy storage station was calculated by numerical integration, which could make it quit operation as early as possible ensuring the stability of the power grid. Through the simulation of Power System Analysis Synthesis Program, the accuracy and engineer-practicability of the theory are verified.
