摘　　要：为研究电力系统机电暂态和中长期动态过程中储能电池对电网的影响,提出一种电池储能系统的多时间尺度仿真模型,并针对每个组成部分进行了详细建模。该模型在大型电力系统分析软件包的全过程仿真程序PSD-FDS中得到了实现,并通过算例验证了模型的有效性,为储能电池系统的并网研究提供了仿真手段。在此基础上,该文对电池储能系统展开了不同时间尺度下的特性分析,研究了其机电暂态特性及中长期动态特性,以及电池储能系统的接入对电网的影响。仿真显示电池储能系统对电网的稳定性有改善作用,且可以有效地平抑新能源发电的功率波动。To analyze the electro-mechanical transient, mid-term and long-term dynamic impact of battery energy storage system （BESS）, this paper proposed a multi-time scale model of BESS, whose components were described in detail. The proposed model was realized in PSD-FDS program and verified by samples, and it provided simulation tools for analysis of grid-connected BESS. Based on the model, numerical researches were carried out on multi-time scale performance of large-scale grid-connected BESS, and its electro-mechanical transient, mid-term and long-term characteristic and grid-connected impact were analyzed. The simulation results show that BESS can improve the stability of power system and smooth the fluctuations of new energy power generation effectively.
