Embodiment Construction
[0059] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.
[0060] The embodiment of the present invention provides a method for identifying vulnerable coupling links between a power grid control system and primary power equipment. The method is composed of four parts: (1) Establishing a dependent coupling network model between a smart grid control system and a primary power system according to actual conditions; (2) According to the impact of physical grid electrical constraints and topological characteristics on the observability and controllability of smart grid control systems, construct a vulnerability point identification method based on node centrality; (3) Construct a method based on "physical domain-information domain" Comprehensive risk measurement indicato...
