含分布式电源配电网启发式孤岛划分方法

heuristic islanding algorithm based on distance-weight was proposed in this paper. This algorithm takes the maximum recovered critical load as the main target, introducing distance-weight which represents the distance between the objective load and the island, starting with DG nodes, based on BFS theory, and merging the nearest load by turn in the end. Considering the impact of controlled loads, the initial islands only contain important loads and uncontrolled loads. The ordinary controlled loads will be merged into islands in turn according to active power, followed by security assessment. Simulation results have demonstrated that the proposed algorithm can achieve optimal island partitioning quickly, which proved the effectiveness of the proposed method.
