摘要
针对含电池储能系统(batter energy storage system,BESS)的配电网参与电网仿真所需的广义综合负荷模型展开研究。阐述了BESS的仿真数学模型,搭建了基于MATLAB/Simulink的BESS仿真平台;通过对BESS暂态运行特性的仿真分析,提出了一种面向负荷的BESS等效模型并进行了检验;建立了考虑BESS的配电网广义综合负荷模型,该广义综合负荷模型由BESS等效模型和经典综合负荷模型(composite load model,CLM)并联构成;通过多场景的仿真分析,检验了提出的广义综合负荷模型的有效性和模型参数稳定性。
We studied the generalized composite load model for distribution network containing a battery energy storage system(BESS)to participate in power grid simulation,expounded the simulation mathematical model of BESS,and established a BESS simulation platform based on MATLAB/Simulink.Through the simulation analysis of transient operation characteristics of BESS,we put forward and verified a load-oriented BESS equivalent model,and then proposed a generalized composite load model of distribution network considering BESS,which is composed of the BESS equivalent model and the classical composite load model in parallel.Finally,the validity and parameter value stability of the proposed generalized integrated load model are verified by multi-scenario simulation analyses.
