In order to reduce the power outage loss of the grid after a large area power failure in the regional power system, it is necessary to start the black power grid as soon as possible. For distribution networks with distributed generation (DG), it is of great significance to determine the partition scheme of islands and put forward the black start strategy of DG to continue to supply power to the loads, so as to reduce the power outage loss. Fully considering the importance of loads and their controllability, an island partition scheme of two steps are proposed based on the established mathematical model. The primary island is formed by using the dynamic programming algorithm, and then, the secondary island is formed by modifying primary island according to certain rules, thus obtaining the optimal island. Then the starting sequence of the black start power supply in the island is determined by Analytic Hierarchy Process (AHP) and the black start strategy is obtained. The effectiveness of the proposed island partition and black start strategy is verified by using the example of PG&E69-node system.
