Importance Assessment of Cyber Devices Considering Effective Distance Based Closeness Centrality
摘要
Abstract
In the cyber-physical power system (CPPS),the failure or malicious attack on cyber system may cause load loss in the physical system.To solve this problem,a method considering the effective distance based closeness centrality for analyzing the importance of cyber devices is proposed.Firstly,a weighted digraph is abstracted from the cyber system for quantitative analysis.Then,the weight of each edge is calculated based on the reliability influence of cyber system on the physical system. After that,the concept of effective distance is introduced to evaluate the closeness centrality via effective distance for each node,which can quantitatively analyze the cyber device importance from the perspective of load loss.Finally,by sorting the importance degrees of cyber devices in the testing system,the effectiveness of the method is verified.关键词
