The Design of Holistic Vulnerability Measure Method Integrated with Topological Properties and Security Capabilities for Smart Grid Control System

In order to improve the overall security operation of smart grid, this paper designs a holistic vulnerability measure method for smart grid control system that integrated with its topology properties and security protection capabilities. More detailed, the method can intensively assess its vulnerability through the featured indexes, i.e., the inherent topological vulnerability indexes in terms of the local uniformity and global imbalance rooted from the internetworking of smart grid control system, the interdependent vulnerability indexes induced from power grid in terms of electrical centrality of power nodes, and the intrinsic security defects stemmed from smart grid control system in terms of the attacking effectiveness. Besides, this paper implements its vulnerability situation visualization by radar map, and computes a weighted value to effectively evaluate its holistic vulnerability. Finally, through a case of the smart grid IEEE14-bus, this paper verifies the effectiveness of the proposed vulnerability metrics and the measuring method. ¹
