考虑风电机组的时变故障率和降额率以及风电场复杂尾流效应的影响，建立了风电场的出力模型；考虑电池储能的充放电约束和容量约束以及其故障率的影响，建立了电池储能系统的出力模型。综合上述2个出力模型，考虑不同风能调度策略得到了含电池储能风电场的出力模型。基于该模型给出了含电池储能和风电场的电力系统风险评估的具体流程和方法。改进IEEE-RTS 79算例仿真和分析，验证了上述模型和方法的正确性和有效性。

The output model of wind farm is proposed taking account into the time-varying characteristics of failure rate and derating rate for wind turbines and the complex wake effects of wind farm. The output model of battery energy storage system is proposed considering the charging and discharging constraints, capacity constraints and forced outage rate of the battery energy storage. And then combining the proposed output models, the integrated model of wind farm can be proposed based on different scheduling strategies of wind farms. According to the integrated model, the risk assessment processes and methods are given. The calculation and analysis of improved IEEE-RTS 79 case was carried out, and the simulation results verify the effectiveness of the proposed model and the method.
