Coordinated recovery method of post-disaster distribution network cyber-physical system considering network reconstruction and emergency resources

In recent years，the frequent occurrence of extreme weather disasters has seriously affected the cyber-physical system of distribution network. Therefore，the coordinated recovery of distribution network and information network after disaster is of great importance. In order to reduce the loss of post-disaster system，a multi-source coordinated recovery method for distribution network cyber-physical system with the goal of minimizing the system loss cost. A post-disaster coordinated system recovery model is established based on the coupling of distribution network and information network，and then measures such as distributed generator set，energy storage equipment，network reconstruction and mobile emergency resources are taken into account to accelerate load recovery. On this basis，considering the uncertainty of new energy output，a multi-source coordinated recovery method for distribution network cyber-physical system after disaster based on information gap decision theory is proposed. The simulation of IEEE 33-bus distribution network and 21-node information network is carried out to verify the effectiveness of the proposed method. © 2024 Electric Power Automation Equipment Press.
