Abstract: With the development of distribution networks, the widespread use of communication devices has exposed these networks to the risk of cross-domain attacks. Based on the coupling relationship between power and communication networks, a method for the optimal allocation of distribution network resources considering this coupling is proposed. In the resource allocation stage, given the limited availability of resources, optimal allocation is carried out for resources such as distributed generations and remote-controlled switches; additionally, the resilience of the distribution network is enhanced through the reinforcement of both the distribution lines and communication links. In the prevention stage, in advance of extreme events, preventive islanding is formed through switch operations. In the degradation stage, the distribution network identifies faulted and non-faulted areas based on the fault propagation model, while the communication network assesses the fault status of communication nodes based on the virtual flow model. In the recovery stage, coordinated control of remote-controlled switches and distributed generations with normal communication is implemented for network reconfiguration to minimize load losses. Finally, the effectiveness of the proposed method is verified through the IEEE 33-node system.
