Optimization Decision-making Method for Emergency Repair and Restoration of Transportation-distribution Networks Based on Ant Colony Algorithm
After the power outage caused by extreme events,the damaged traffic roads will affect the progress of the grid re-pair team to the fault line area,thus delaying the restoration of the distribution networks.For this reason,a method of distribu-tion network emergency repair and restoration combined with the repair of damaged roads was proposed.Firstly,the con-straints of rush repair vehicles in the traffic network were con-structed based on the analysis of the impact of different dam-aged roads on rush repair vehicles.Secondly,considering the impact of damaged road emergency repair on power grid emer-gency repair,taking minimizing power loss of distribution net-work as an objective,line emergency repair and road repair was coordinated to establish a distribution network emergency re-pair strategy model,which was solved by ant colony algorithm.Finally,a system coupled with IEEE33-node distribution net-work and a 12-node transportation network was taken as an ex-ample for analysis.The simulation results show that the pro-posed method effectively improves the speed of distribution network emergency repair and reduces the power loss of distri-bution network load after a major power outage.The proposed scheme is more suitable for the actual situation of disasters,and can provide reference for the post disaster recovery of distribu-tion network.
