Abstract

In a Cyber-Physical Power System (CPPS), cyber attackers can invade the cyber equipment through communication weak points, resulting in the illegal removal of equipment in the physical layer, forming a cross-domain attack from the cyber layer to the physical layer. This paper establishes a CPPS model based on interdependent network theory and proposes a comprehensive vulnerability assessment method based on the Bayesian attack graph. The vulnerability nodes in the power grid are searched to assess cyber-attacks. Finally, the effectiveness of this method is verified based on the IEEE-14 bus system.
