基于双模式功率互济的配电网多故障抢修优化策略OA

This article proposes a layered coordinated emergency repair optimization strategy based on dynamic virtual microgrid partitioning and flexible resource power mutual assistance to address the problem of rapid load recovery after multi period faults in distribution networks under extreme weather conditions.First,a differentiated dynamic microgrid partitioning model of"source-critical-normal"is constructed and a dual-mode power mutual assistance mechanism of"fixed interconnection switch+bypass load switch(BLS)"has been designed to improve load recovery flexibility.Second,a collaborative scheduling model is established with the goal of minimizing load loss and total recovery costs—including those associated with maintenance teams,BLS,mobile emergency generation(MEG)and contact switches—to optimize scheduling plans.Finally,the proposed method is validated through simulations on the IEEE 33-node system under multi-temporal and multiple fault scenarios.The results show that the model proposed in the article can adaptively adjust the virtual microgrid topology,fully utilize the flexible load allocation capabilities of BLS,and exploit the fast power support characteristics of MEG.This approach improves fault response speed and recovery efficiency while ensuring power supply reliability.Additionally,the utilization rates of maintenance teams and BLS are significantly higher than those of MEGs,achieving coordinated complementarity and cost-effective use of multiple resources.
