[0002] With the continuous adjustment of the global energy structure and the rapid development of renewable energy technology, microgrid distributed power supply, as a new energy supply model, is gradually gaining widespread attention. Microgrid distributed power supply technology is based on the traditional power system and combines modern power electronics, network communication and intelligent control technologies to achieve decentralized production, transmission and consumption of energy.

[0003] Microgrid is a small power generation and distribution system composed of distributed power sources, energy storage devices, loads and monitoring and protection devices. It can be operated in an isolated island or connected to the grid. Microgrid technology uses intelligent control strategies to achieve energy balance and optimization management within the microgrid, and coordinates and interacts with the main grid to ensure the stable operation of the power system. Solar energy, as a clean and renewable energy, is gradually becoming an important part of microgrid distributed power sources. Solar energy technology, with its unique advantages, provides a strong impetus for the development of microgrid distributed power sources.
