Analysis and Research on Microgrid Energy Storage System Based on “Source Network Load Storage“

This paper researches the topology and control methods of the “source network load storage” microgrid energy storage system, and analyzes the impact of complex operating conditions on the system. We construct the topology structure of photovoltaic power generation and wind power systems, as well as a microgrid system structure based on “source grid load storage”. The control method of microgrids usually adopts hierarchical control to improve the response speed and accuracy of system control strategies. Analyzing the impact of various complex working conditions such as changes in external lighting, environmental wind speed, and system reactive power on photovoltaic power generation systems and direct drive wind power systems lays a solid foundation for further in-depth research on microgrid energy storage systems.
