Abstract
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.
