摘要
针对风电功率的随机波动性,采用储能系统改善风电机组的并网运行特性。文章分析了蓄电池储能系统的基本原理及其控制策略,并基于电磁/机电暂态混合仿真程序DIg SILENT/Power Factory搭建了对应的储能系统模型,将其配置在双馈型风电场出口母线的公共连接点处。分别在风速随机波动以及电网侧发生故障的工况下,研究所建储能系统的动态响应特性,结果表明,储能系统可以减小风电输出功率的波动对电网的影响,并能提高风电场并网的稳定性。
The energy storage system （ESS） can improve output power performance of wind turbines that are connected to grid. The basic principle and control strategy of battery energy storage system （BESS） are introduced, then the corresponding models are built in DIgSILENT/PowerFactory. The dy- namic responses of the BESS under different wind fluctuations and the fault conditions of the grid are studied, the simulation results show that the ESS can reduce the impact of wind fluctuations on the grid, the stability of the grid-connected wind farm is also improved.
