Abstract:
With the development of cyber-physical power system, cyber security has a serious impact on the operation of power system. In this paper, a stochastic cascading failure model considering the structural and dynamical characteristics of cyber-physical power system is proposed. The model takes into account the community structure of networks, the heterogeneity of network nodes and the complex interdependence of coupling networks. Moreover, the malware spreading in the cyber network and the power flow redistribution in the power grid are considered to describe the dynamic physical processes of the system, and a stochastic method is adopted to describe the operating state transition of network components. Simulation results indicate that the cascading failure of coupled system is the result of malware attacks repeatedly triggering the power grid, and cyber coupling will aggravate the severity of grid failure propagation.
