提高配电系统韧性的遥控开关与传统开关的优化配置方法

The Optimal Configuration Method of Remote Control Switch and Manual Switch to Improve the Resilience of Power Distribution System

  • 摘要: 为快速恢复负荷供电,增强配电系统的韧性,通常考虑网络重构技术。传统开关(Manual Switch,MSs)的开闭状态无法快速改变,系统故障发生后不久的恢复阶段,其状态由防御阶段的状态决定,而配备遥控开关(Remote-Controlled-Switch,RCSs)的配电系统,其网络能够快速重新配置。考虑到这些因素,本文提出提高配电系统韧性的遥控开关与传统开关的优化配置方法。为实现传统开关和遥控开关的有效分配,本文综合考虑了通过RCS和MS进行防御阶段网络配置和基于RCSs的恢复阶段快速网络配置。将该方法应用于IEEE 33节点母线系统,并验证了其有效性。

     

    Abstract: Network reconfiguration is often considered for fast load restoration to enhance distribution system resilience. For distribution systems equipped with remote-controlled switches (RCSs), the network could be reconfigured more fast. Nevertheless, when there is a manual switch (MS), its closed or open state cannot be changed quickly, and its state in the restoration stage shortly after faults is determined by state in the prevention stage. Given these facts, the coordinated allocation of RCSs and MSs for is considered for resilience enhancement in this paper. To make the allocation of RCSs and MSs more effective, the network configuration of the prevent stage through RCSs and MSs and the fast network configuration of the restoration stage based on RCSs are comprehensively considered. The proposed method is applied on the IEEE 33-bus system and its effectiveness is verified.
