摘要网络重构技术是实现智能配电网自愈控制功能最重要的手段之一,而避免重构中生成不满足拓扑约束解是实现快速重构最重要的关键点。分别以单馈线IEEE 33节点系统及多馈线的实际配电网系统作为算例,并针对二者不同的拓扑结构提出不同的负荷均衡优化目标函数。通过分析已有避免不可行解方法的缺陷,提出了4个编码规则,并将其与和声算法有机融合,以实现无不可行解产生的快速网络重构。通过仿真验证了该方法的正确性、可行性以及工程实用性。

Abstract：Network reconfiguration technology is one of the important means to achieve distribution system self-healing,and the key point of which is avoiding infeasible solutions.In this paper,different load balancing objective functions are proposed for IEEE 33-node system with a signal feeder and practical distribution system with several feeders.Four encoding rules applied in the harmony search algorithm are presented for avoiding infeasible solutions during the network reconfiguration after analyzing the drawbacks of the exiting methods.The accuracy,feasibility,and engineering practicality of the proposed method to avoid infeasible solutions is proved by the simulation results.

Key words： Network reconfiguration harmony search algorithm encoding rules avoiding infeasible solutions
