Research on power-communication coordination recovery strategy based on grid dividing after extreme disasters

Abstract

Extreme natural disasters will cause great damage to the power and communication systems of the distribution network. During the restoration process of the distribution network, the power and communication systems interact and restrict each other. The coordination of the two can make the distribution network restore effectively and quickly. To improve the recovery speed and efficiency of the distribution network after disasters, power-communication coordination recovery strategies based on gridding method after disasters are proposed. Firstly, according to the corresponding relationship between mobile base stations and power nodes, multi-level grids of distribution networks are divided, and power-communication coordinated recovery models of distribution networks are respectively established aiming at short rush repair time and small power outage loss. On this basis, a coordinated recovery strategy of power-communication is proposed in combination with the gridding method. Finally, the IEEE33-node distribution network system is taken as an example to verify the necessity of the gridding method and coordinated power-communication recovery and the effectiveness of the proposed method.
