随着电池储能系统在电网中应用日益广泛,配电网综合负荷特性应当计及电池储能系统的动态特性,建立适用于广义负荷建模的电池储能系统仿真模型。基于软件仿真环境搭建了电池储能系统并网仿真平台,研究了电池储能系统在并网母线处的动态特性,提出了一种含电压源、电阻以及惯性环节的电池储能系统的外特性等效模型;分析了提出模型在泛化能力方面的不足及其原因,在此基础上,提出了一种基于模型参数修正的改进模型结构。仿真结果表明,提出的模型能较好地描述电池储能系统的动态特性,而改进模型则有效提高了提出模型的泛化能力。

With the increasing application of the battery energy storage systems in power grid, the comprehensive load characteristic of distribution network should consider the dynamic characteristics of the battery energy storage system, and establish the battery energy storage system model suitable for load modeling. This paper builds a gird-connected the battery energy storage system in software simulation environment. An external characteristic equivalent model of the battery energy storage system consisting of a voltage source, a resistance and an i...
