Abstract: In order to further improve the operational reliability of the microgrid with renewable energy, it is fully considered that the high-permeability microgrid can be in a normal operating state in the grid-connected mode and the island mode. In this paper, the black-start strategy is considered to restore the normal power supply of the microgrid with renewable energy in the island mode, and the operation status of the microgrid under different operation conditions is compared through mathematical modeling and simulation analysis, which further verifies the feasibility and effectiveness of the black-start strategy of the microgrid with renewable energy proposed in this paper.
