Comprehensive vulnerability assessment and optimization method for smart grid communication transmission systems

摘要

Vulnerability assessment and optimization for wide area monitoring, protection and control system (WAMPAC) can enhance the robustness and sustainability of network. However, current assessment methods are incomplete and optimization methods ignore dynamic process. A comprehensive vulnerability assessment and optimization method is proposed. Firstly, for assessment, a comprehensive vulnerability indicator is designed to assess vulnerability of nodes and edges in the network integrating static and dynamic aspects. And then, to relieve unbalanced vulnerability distribution in the network, a routing optimization method is proposed by reconfiguring service routes on the edge with high vulnerability. Finally, the simulation is taken under a real system. Vulnerability assessment with the defined indicator is executed, and its correctness is proved as well. Then with the optimization method, the network vulnerability can be balanced, which takes on effective theoretical and practical significance.
