摘　　要：将锂电池储能系统应用到风力发电中,并针对锂电池储能系统的运行特性,提出了一种可行的综合控制策略。仿真结果表明,锂电池储能系统在电网正常运行时能够快速、有效地平滑风电系统输出的有功功率波动;在电网故障时能够为电网提供一定的无功支持;在脱离电网运行时能够稳定系统的电压和频率,有效地提高了风电系统的运行性能。In this paper,lithium battery energy storage is applied in the wind power system.Based on the operating characteristics of lithium battery energy storage,a feasible integrated control strategy is proposed.The simulation results indicate that when the grid operates normally,the lithium battery energy storage can smooth output active power fluctuations of the wind power system quickly and effectively.On the other hand,when grid faults occur,the lithium battery storage is able to provide a certain degree of reactive power support for the grid.Moreover,when the system operates grid-isolatedly,the storage can help stabilize the system voltage and frequency,enhancing the operation performance of the wind power system effectively.
