Intermittent power sources such as photovoltaic power and wind turbine are used as the power supply for recovery of distribution system. Firstly, an operating criterion for the complementary joint operation of power supply systems is proposed to combine the complementary power supply systems. Then, a method of island division is proposed, which combines Floyd algorithm and Prim algorithm and considers the shortest path of power supply. On this basis, the fault recovery process considering the complementary characteristics of multi-source islands is designed. The results of calculation examples show that the proposed power supply fault recovery method considering the complementary characteristics of multi-source islands can not only effectively reduce the impact of intermittent power output fluctuations on the recovery capacity of the island, but also recover more loads and improve the recovery effect.
