Abstract: This paper describes a comprehensive review of microgrid control mechanism and impact assessment for hybrid grid. Building the model of sustained energy. Microgrids are defined as an electrical system that has loads and generation sources that can operate in parallel with the main utility grid, or, in an islanded state, physically separated from the grid. While traditionally thought of as a means of backup power, microgrids can also provide energy. Authorized by Section 40101(d) of the Bipartisan Infrastructure Law (BIL), the Grid Resilience State and Tribal Formula Grants program is designed to strengthen and modernize America's power grid against wildfires, extreme weather, and other natural disasters that are exacerbated by the climate. Wood Mackenzie previews new microgrid research that it will unveil at Microgrid 2023. But new data by Wood Mackenzie indicates that residential microgrids are displacing the retail sector. Much of North America's central power grid transmission infrastructure was built in the 1960s and 1970s. A significant 70% of transmission lines are nearing the end of their typical 50- to 80-year lifespan. The research status of the four control strategies,namely peer control,master-slave control,hierarchical control and decentralized controlis described respectively.
