孤岛运行与拓扑重构相互协调的故障配电网韧性提升策略
A Strategy for Improving the Resilience of Fault Distribution Networks Considering the Coordination of Island Operation and Topology Reconstruction
摘要
Abstract
The varying degrees of power outages caused by extreme disasters have posed challenges to the power system's resilience from failures.The participation of various types of distributed power sources and interconnection switches brings possibilities for improving the reliability of power supply in the distribution network after faults,meanwhile,bringing possibil-ities to enhance the resilience of the distribution network in the face of extreme disaster scenarios.For that reason,a fault re-covery strategy for island reconstruction was proposed,which adopts mixed-integer second-order cone planning and utilizes the coordinated operation strategy of island operation and topo-logy reconstruction for the recovery of critical loads.And a comprehensive evaluation index for the resilience of the distri-bution network after fault recovery was proposed,so as to quantitatively evaluate the resilience through these three as-pects:resistance stage,recovery stage,and resilience evalu-ation.Finally,taking the improved IEEE 33 node distribution system as an example,the effectiveness of the proposed co-ordination strategy for fault recovery in distribution networks was verified,as well as the resilience evaluation index for resi-lience evaluation after fault distribution network recovery.关键词
