Abstract: This study takes the demonstration project of "photovoltaic energy storage and charging" microgrid in an industrial park in Gansu Province as an example, and deeply explores the design and application effect of a layered distributed integrated energy management technology for wind solar energy storage. Through engineering verification, it has been found that this scheme has significant optimization effects on smoothing out fluctuations in renewable energy output, improving source load matching, and optimizing energy storage operations. The application results show that the system can solve problems such as strong resource volatility, poor load matching, and extensive energy storage operation, and has certain promotional significance for improving the economy, safety, and green energy consumption level of microgrids in the park.
