考虑交通网延误的配电网灾后滚动抢修策略优化

Optimization of Post-disaster Rolling Emergency Repair Strategy for Distribution Network Considering Transportation Network Delay

  • 摘要: 为解决当前配电网灾后抢修策略制定时,未充分考虑道路阻断和交通延误影响抢修进程的问题,提出了考虑交通网延误的配电网灾后滚动抢修策略。首先,建立了计及交通网延误的灾后滚动抢修策略框架,以道路延误函数与路口延误函数建立实时交通网延误模型,通过Floyd算法得到各故障点间最短通行时间矩阵。其次,建立考虑交通网延误的灾后抢修策略双层优化模型,外层以加权失电负荷最小和抢修总时长最短为目标,得到各抢修班组抢修链。内层以最大化恢复失电负荷为目标,得到紧急恢复方案。在抢修过程中根据交通网信息更新最短通行时间矩阵,滚动后续抢修策略。最后,通过算例仿真验证灾后滚动抢修策略的有效性。

     

    Abstract: To cope with the defect during the enaction of current post-disaster emergency repair strategy for distribution network, namely such problems in the urgent repair as the blocked roads and traffic delay that had not been fully considered, a post-disaster rolling emergency repair strategy for distribution network, in which the traffic network delay was considered, was proposed. Firstly, a post-disaster rolling emergency repair strategy framework, in which the traffic network delay was taken into account, was established, and by use of road delay function and intersection delay function a real-time traffic network delay model was constructed, and by means of Floyd algorithm the shortest transit time matrix among fault points was obtained. Secondly, a two-layer optimization model of post-disaster emergency repair strategy, in which the traffic network delay was considered, was established, in the outer layer the minimum weighted power loss load and the shortest total emergency repair time were taken as the objectives and the emergency repair chain of each emergency repair team was obtained; in the inner layer the maximized recovery of the power loss load was taken as the objective and the emergency recovery plan was obtained. During the emergency repair process the shortest transit time matrix was updated according to the traffic network information, and the follow-up emergency repair strategy was rolled out. Finally, the effectiveness of the post-disaster rolling emergency repair strategy is verified by example simulation.
