Comprehensive vulnerability assessment method based on power communication network structure and state

Abstract

The invention discloses a comprehensive vulnerability assessment method based on a power communication network structure and state, and the method comprises the following steps: 1, obtaining the impact on the assessment of the vulnerability of the power communication network structure from the vulnerable features of the power communication network structure; 2, obtaining the impact on the assessment of the vulnerability of the power communication network structure from the operation state features of a power communication network; 3, integrating the impact on the assessment of the vulnerability of the power communication network structure from the structural characteristics and operation state features of the power communication network, and obtaining a final power communication network vulnerability assessment result. The method achieve the technical effects that the method can locate a vulnerable link in a network more comprehensively after the integration of the current operation state of the network, and can carry out the vulnerability assessment according to different network topologies and operation states.

Description

technical field [0001] The invention relates to the field of vulnerability assessment of power communication networks, in particular to a comprehensive vulnerability assessment method based on the structure and status of power communication networks. Background technique [0002] As the supporting network of the smart grid, the safe and stable operation of the power communication network has become a prerequisite for the intelligent, economical and safe operation of the smart grid. As for the vulnerability assessment of power communication network, the methods currently used to assess the vulnerability of power communication network include, based on the theoretical knowledge of complex networks, using certain indicators such as betweenness and closeness to evaluate the vulnerability of network units, or according to the theoretical indicators of complex networks , Integrating the impact of the power station, analyzing the vulnerability of network units, the power communicat...
