Review of Power Emergency Repair Strategy after Typhoon Disaster

Typhoon may damage the power system and cause huge economic losses. Making appropriate emergency repair strategies can greatly reduce the damage caused by typhoon. This paper presents a detailed review the previous research on power emergency repair. First of all, this paper reviews emergency repair of power system after Typhoon. How to locate the repair-unit stations and find the shortest path is the focus of this research. Secondly, this paper introduces the application of vehicle routing problem in electric power emergency repair. The combination of vehicle routing problem and power emergency repair can make the formulation of emergency repair strategy simple. Finally, this paper summarizes the solution of vehicle routing problem. Compared with the precise algorithm, heuristic algorithm is widely used because of its fast convergence. In the future, intelligence and information are the direction of electric power emergency repair process. The combination with computer intelligence can better allocate resources, help decision makers to make plans quickly and reduce the losses caused by typhoon disasters.
