| 摘要: |
| 配电网发生故障后，失电区域内应该形成含分布式电源(DG)的电力孤岛保证负荷供电的连续性。在孤岛形成算法中充分考虑负荷等级及其可控性，建立孤岛划分问题的数学模型，并利用动态规划算法形成含单DG或多DG组合的初级孤岛划分方案；根据一定的规则修正初级孤岛，形成次级孤岛；校验岛内各负荷点的电压和潮流约束，确定最优孤岛。算例验证了所提模型的有效性和优越性。 |

| Abstract: |
| Power islands with DG(Distributed Generation) should be formed in the de-energized areas of a distribution network with incident to continue the power-supply for loads. A mathematic model is built, which fully considers the level and controllability of loads in its islanding algorithm, applies the dynamic programming algorithm to set the primary islanding scheme with single or multiple DGs, modifies it according to some rules to form the secondary islanding scheme, and checks the constraints of voltage and power flow for each load node in the islands to determine the optimal islanding scheme. Case study verifies the effectiveness and superiority of the proposed model. |
