考虑动态互联微电网与网络重构的弹性配电网多源序贯协同供电恢复方法
Multi-Source Sequential Coordinated Power-Supply Recovery Method for Resilient Distribution Networks Considering Dynamic Networked Microgrids and Network Reconfiguration
摘要
Abstract
[Objective]After multiple line failures,a distribution network can maintain load supply by forming multiple microgrids.The initial formation and subsequent dynamic interconnection of microgrids require consideration of frequency-voltage control and sequential coordinated output of various types of resources.Hence,this paper proposes a multi-source sequential coordinated power-supply recovery method for post-disaster distribution networks,incorporating droop-control-based dynamic networked microgrid technology and network reconfiguration methods.[Methods]First,a pre-disaster electric vehicle dispatch model is established,considering the impact of impending extreme events on user travel intentions.Subsequently,a sequential power-supply recovery model is established that comprehensively considers the output of distributed resources,reverse charging of electric vehicles,repair crew dispatch,and flexible load management with the integration of frequency-voltage control constraints.Finally,multiple sets of examples are designed to validate the proposed method.[Results]The dynamic networked microgrid technology incorporating droop control can reduce the load-shedding ratio during faults to 30%of that without considering dynamic interconnections.[Conclusions]This effectively lowers the amount of load shedding while ensuring the safety of load restoration,providing an important reference for power-supply recovery of distribution networks under extreme events.关键词
