Coordinated Repair and Restoration of Distribution and Communication Networks under Extreme Disaster

In recent years, extreme weather events such as typhoons and earthquakes have posed serious threats to the safe and reliable operation of distribution networks, leading to equipment failures and damaging communication networks. To enhance the resilience of distribution networks, this paper proposes an optimized restoration strategy that by constructing a coupled model of both networks, the proposed approach takes into account optimal path planning. By constructing a coupled model of both networks, the proposed approach takes into account optimal path planning for repair teams, mobile power dispatch, and prioritization of critical loads. The goal is to coordinate the restoration of distribution and communication networks after extreme events by deploying emergency repair resources and optimizing repair sequences. Simulation results indicate that the proposed joint restoration strategy significantly accelerates the recovery of critical loads post-disaster, reduces outage losses, and effectively enhances both the recovery efficiency and resilience of the power grid.
