Coordinated Optimization of Fault Recovery and Emergency Repair for Distribution Network Con-sidering Resilience Improvement
In recent years,more and more attention has been paid to the resilience of the distribution network in response to natural disasters,emergencies and other disturbance events.In order to enhance the post-disaster recovery capabilities of distribution network in response to extreme events,we introduced a coordinated optimization strategy that focused on fault recovery and emergency repairs,with resilience improvement as a key consideration.Initially,a bilayer optimization model that integrated fault recovery and emergency repair strategies was constructed.This model not only emphasized system resilience during the repair process but also prioritized the restoration of critical loads upon completion of the re-pairs.Furthermore,an enhanced Harris Hawks Optimization algorithm to solve the emergency repair model was proposed,determining the most effective repair sequence.Based on the results above,this paper iteratively devised solutions for is-land partitioning and switch reconfiguration in the distribution network following extreme events.This holistic approach aimed to formulate the optimal post-disaster repair strategy for the distribution network.To validate this strategy,we conducted simulations using the IEEE 33-node system.The results verify the effectiveness of the strategy in harnessing the synergistic relationship between fault recovery and emergency repairs,thereby significantly enhancing the resilience of the distribution network in post-disaster scenarios.
