英文摘要：

In this case,the outage model of the electrolytic capacitor was introduced into the wind farm battery storage capacity optimization,and the process of the outage was simulated by the model. Then the paper established the output model of energy storage system according to the power of battery and the outage model of the power conversion system（ PCS）. Based on the sequential simulation of battery energy storage system,the optimization model of the energy storage capacity of the wind farm was built with the minimum cost as the objective function. And the model considers the maximum charge-discharge times and the loss of wind energy,etc. Then the problem was solved using PSO algorithm,and the result shows that the method is effective.
