Modeling and Simulation of Photovoltaic System Based on Large-capacity Battery Energy Storage Technology

摘要

The high intermittency and fluctuation of the power output of photovoltaic system is owing to the influences from the sunshine,temperature and other external environment.Thus certain energy storage devices are equipped in the actual application to improve the dynamic and static characteristics of the whole system.This paper studied and analyzed the characteristics of large-capacity battery storage technology.The reliability and stability of the principle design of BES-PVGCS and the power control strategy by modeling and simulation were verified.
