基于改进功率树的含分布式电源配电系统孤岛划分
Island Partition of the Distribution System with Distributed Generations Based on Improved Power-tree
摘要
Abstract
It is necessary to formulate a strategy quickly to ensure the power supply for key loads as soon as possible af?ter the occurrence of fault in distribution system. In this paper,a novel island partition model of the distribution system with distributed generations(DGs)is proposed,together with an improved method of power-tree. A three-step strategy containing partition,solution and adjustment is applied:firstly,fundamental power-trees are formed,and operations such as merging,expansion,deletion and update are realized by using the improved method,thus the power-tree blocks with the maximum regions,which are feasible to restore the power supply,are formed;then,the power-trees are processed one by one by using the binary combination/mutation particle swarm algorithm;finally,the formed parti?tion scheme is analyzed and adjusted to ensure that the island can operate stably. With the consideration of constraints such as the priorities of loads,power balance,nodal voltage and network topology,the proposed model can meet the practical requirement and find the global optimal partition scheme quickly. The calculation results of a case study dem?onstrate the validity of the proposed method.关键词
