| 中文摘要: |
| 针对光伏、风机等间歇性电源作为配电系统供电恢复电源的情况，首先提出电源系统互补联合运行判据，将具有互补特性的电源进行联合运行；然后提出一种结合Floyd算法与 Prim 算法、考虑电源最短路径的孤岛划分方法；在此基础上，设计了考虑多源孤岛互补特性的故障恢复流程。算例结果表明，所提出的考虑多源孤岛互补特性的供电故障恢复方法，可以有效减小间歇性电源的出力波动对孤岛恢复容量的影响，能够恢复更多负荷，提升恢复效果。 |
| 英文摘要: |
| 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. |
