台风灾害下计及负荷恢复优先级与动态修复的配电网韧性优化与评估方法
Method for Resilience-oriented Optimization and Evaluation of Distribution Networks Considering Load Restoration Prioritization and Dynamic Repair Under Typhoon Disasters
摘要
Abstract
[Objective]To enhance the resilience of distribution networks under typhoon disasters and mitigate the risks of load interruptions and power supply losses caused by natural disasters,this paper proposes a resilience-oriented optimization strategy and evaluation method that accounts for load restoration priority and dynamic repair.[Methods]Typhoon-induced fault scenarios are constructed by integrating the Batts typhoon model with a line fault model,thereby capturing the impacts of typhoon intensity and trajectory on distribution networks.On this basis,a multi-source collaborative optimization model is developed with the core objective of prioritizing the restoration of critical loads.The model couples dynamic reconfiguration,fault repair,and the dynamic output characteristics of distributed energy resources(DERs)to enable rapid response and efficient resource dispatch during disasters.A set of resilience evaluation metrics of load average recovery level considering load weights is proposed to quantitatively evaluate system resilience under different scenarios.[Results]Case studies on a modified IEEE 33-bus distribution system demonstrate that the proposed strategy effectively reduces overall system load losses and significantly improves the restoration level of critical buses and essential users under typhoon scenarios.The simulation results also validate the applicability and effectiveness of the proposed evaluation metrics in distinguishing the merits and demerits of different recovery strategies.[Conclusions]The proposed strategy achieves dynamic optimization of distribution networks throughout the disaster impact and recovery process.Compared with conventional approaches,it exhibits distinct advantages in terms of load restoration speed,supply reliability,and resource utilization efficiency.In addition,the proposed resilience evaluation metrics provide a more scientific characterization of system resilience under disaster conditions,compensating for the limitations of conventional metrics.Overall,this paper offers valuable insights and references for fault recovery and resilience evaluation of future power systems under typhoon disasters.关键词
