摘　　要：在PSCAD/EMTDC中,搭建经DC/DC变换器及DC/AC换流器并网的电池储能系统(BESS)模型,设计相应的控制策略,并建立恒速恒频、双馈风电机组与BESS相应配置的交流并网仿真模型。针对电网稳态运行及故障情况,设计BESS相应控制策略并分别进行仿真分析,结果表明在变化风速下,BESS灵活有功控制能力可平抑风电场稳态运行时的功率波动;电网故障时,BESS可提供无功支撑稳定并网点电压、提高风电场低电压穿越能力。The simulation model of battery energy storage system(BESS)connected to the power grid with DC/DC converter and DC/AC converter was built,and the control strategies were developed.The wind power generating system with fixed speed induction wind turbines and doubly-fed induction wind turbines connected to the power grid with BESS was built in the PSCAD/EMTDC.According to the steady-state and fault-state of the power gird,the corresponding control strategy of BESS was developed.The research results show that the flexible active power control ability of the BESS can smooth the power fluctuation caused by the changing wind speed.Under the fault-state,the BESS can provide the reactive power support to stabilize the grid voltage and improve the low voltage ride-through(LVRT)ability of the wind farm.
