面向韧性提升的主动配电网灵活调度与故障修复协同策略
A Coordinated Strategy of Flexible Dispatch and Fault Repair for Active Distribution Networks Towards Resilience Enhancement
摘要
Abstract
[Objective]To address the rapid recovery and resilience demands of MV/LV distribution networks in extreme disaster environments,a coordinated strategy integrating the flexible dispatch of active distribution networks and fault repair is proposed.[Methods]First,a multidimensional resilience assessment framework encompassing load restoration efficiency,voltage stability,and socioeconomic loss was constructed.Second,a flexible dispatch model considering user-side flexible resources and the distribution network topology was established,and second-order cone programming and a parallel adaptive ant colony optimization algorithm were employed to achieve the prioritized restoration of critical loads and optimization of the voltage quality.Subsequently,for the fault repair problem,an improved Harris hawks optimization algorithm was designed to optimize the repair sequence of a single repair crew.Finally,a resilience enhancement strategy was formulated through a coordinated optimization model integrating the flexible dispatch of the distribution network and fault repair.[Results]Simulation results showed that the proposed strategy significantly improved the average load restoration speed,resulted in smaller node voltage fluctuations,and reduced socioeconomic losses by approximately 80%compared with other strategies.The improved Harris hawks optimization algorithm was significantly superior to the other algorithms in terms of the convergence speed and optimization accuracy.[Conclusions]The bi-level optimization model established for the dispatch and repair of active distribution networks in this study balanced the restoration speed with operational stability and significantly enhanced the distribution network resilience.关键词
