An Interval Number optimization Method for Post-Disaster Repair of Distribution Network considering Island

In this paper, the optimization method of post-disaster distribution network repair strategy based on interval optimization is proposed. According to the problems existing in the process of repairing, the repair model considering the various uncertainties in the repair process and the corresponding constraints has put forward, in order to reduce the social and economic losses as the ultimate goal. According to the radial structure of the distribution network, topology search is used to quickly find the reoperation area. Through fuzzy equilibrium, the formulation of post-disaster repair strategies is accelerated, and an improved bee colony algorithm is used to find the optimal solution. Finally, a 15-node system is introduced, and the simulation and analysis are carried out on the MATLAB platform to verify the practicability and effectiveness of the optimization strategy.
