Abstract: Power communication network is an important supporting network of smart power grid. According to the complex characteristics of power communication network to identify the structural vulnerability of power communication network, how to carry out comprehensive and effective assessment of its vulnerability, this paper proposes an effective assessment method based on the vulnerability loss of power communication network. Firstly, the topology modeling of power communication network is carried out. According to the static parameter characteristics of the network and the static statistical characteristics of the network, the typical model corresponding to the complex network is pointed out, and its characteristics are summarized and verified. Secondly, considering the physical layer and the network layer comprehensively, the importance loss of the physical layer and the maximum connectivity rate of the network layer are defined, and then the vulnerability loss of the network is finally obtained by giving the corresponding weight value respectively, which is used as the vulnerability evaluation index of the power communication network. Finally, based on the simulation background of the actual power communication network in a province, the effectiveness of the method in this paper is proved by comparing the vulnerability loss of different curves.
