Abstract

To ensure the secure and stable operation of Cyber-Physical Power System (CPPS), research on their topology and robustness is essential. Based on the theory of complex networks, a comprehensive CPPS robustness evaluation framework is proposed, which establishes topological structures and functional cascading failure models, along with corresponding performance quantification metrics. By combining the Louvain algorithm and gravity centrality, a method for identifying the importance of nodes considering the underlying network topology is proposed. Pre-disaster protection measures are implemented based on node importance, and the robustness of the system is compared under different protection strategies. Finally, the CPPS model constructed using the IEEE118 network is used to simulate the system's state response under different conditions, verifying the effectiveness of the proposed method.

Key words： cyber-physical power system; complex network theory; critical nodes; robustness
