Abstract: In order to improve the fault recovery of the distribution network under extreme disasters, this paper proposes a coordinated recovery method that considers the dynamic interaction between power and communication network for disaster faults in the smart distribution network. A complex network model of power-communication coupling in the distribution network is established, and the coupling influence relationship is transformed into the constraints of the fault recovery process. The fault recovery process is divided into two stages: grid reconfiguration and rapid load transfer under communication failure, and dynamic coordination of power and communication repair and comprehensive load recovery. The amount of load recovery that can be brought by power and communication recovery is dynamically quantified, and the process of grid recovery and communication network recovery is optimized to achieve the maximum direct load recovery and transfer recovery in the shortest time. The actual distribution network calculation results show that the proposed method can reduce the recovery time of disaster faults by 7.69% and the loss of power outages by 9.27%.
