Research on Simulation Modeling and experimental technology of large capacity distributed energy storage

Abstract

Distributed energy storage technology has become a very hot and important research problem. However, there is no real-time simulation modeling and experimental analysis method for the operation characteristics of energy storage system connected to power system. Real time simulation is a powerful tool for closed-loop experiment of distributed energy storage. The minimum step size of real-time simulation can reach 1 microsecond, which can meet the requirements of distributed energy storage system simulation research. In this paper, the simulation platform of energy storage system is established. The simulation model which can accurately simulate the energy storage battery and energy conversion system is established. The simulation model can be used to test the control function of energy storage. In this paper, the interface between simulator and energy storage control system is designed.
