Research on the Defense Strategies for Cyber-Physical Power System

The power system has become a typical cyber-physical power systems (CPPS) due to the extensive application of information and communication technology. This paper first analyzes the cyber-attack patterns targeting CPPS, then proposes an optimization model of defense strategies for CPPS based on the -v algorithm, regarding the multi-stage dynamic interaction process between the attacker and the defender as a two-person zero-sum game. The model can enhance the ability of CPPS to resist cyber-attacks by reasonably allocating limited defense resources. The results of simulation verify the feasibility and effectiveness of the proposed model, providing valuable reference for improving the level of network security of CPPS.
