Applied research of battery energy storage in grid-connected photovoltaic power

Discuss and make the application mode of the battery energy storage in grid-connected photovoltaic power system, based on DIgSILENT simulation platform, and establish the model of photovoltaic power and energy storage system, the solar - storage co-generation system operating characteristics on different application modes are simulated and analyzed. The simulation results show that: battery energy storage system can effectively stabilize the output power fluctuations of the grid-connected photovoltaic systems, and help to reduce the impact of photovoltaic power fluctuations on the grid.
