Abstract

With the vigorous promotion of urban energy internet and smart grid, the risk of various malicious cyber attacks on existing cyber physics power systems has increased significantly after they are transformed into integrated energy cyber physics systems（IEGS）. In order to ensure the safe and reliable operation of urban integrated electricity-gas system, this paper proposes a loss assessment model for integrated electricity-gas system under cyber-physical coordinated attack. Firstly, the branch fault scenario is randomly generated, and then the real operation state of the branch is concealed by injecting false data. Secondly, the DC power flow model and probability model are used to simulate the cascading failure of the power system, and the loss caused by the coordinated attack on the urban integrated electricity-gas system is evaluated according to the physical operation characteristics of IEGS, the IEGS vulnerability branch is evaluated. Finally, the correctness and effectiveness of the model are verified by the integrated electricity-gas system composed of IEEE 30 nodes and Belgium 20 nodes.
