Embodiment Construction
[0090] It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.
[0091] Since many infrastructure systems require power networks to ensure their operation and management, in modern information warfare, power networks have become one of the important removal targets for combat units. Therefore, for each power supply in the power network system Unit, the first to predict its importance and its deployed defense capabilities, can provide an important basis for subsequent identification of target nodes.
[0092] At present, the research on the removal resistance of complex networks is mainly based on the identification of important nodes in complex networks, but the current identification methods are mainly based on the premise of "no cost", that is to say, when removing nodes in complex networks, removal is not considered cost. However, such networks are very vulnerable to s...

The present application discloses a method, device, equipment and storage medium for identifying a target node of a power grid. The method includes: obtaining a network simulation model of the power grid to be identified; and obtaining the power grid to be identified based on the network simulation model of the power grid to be identified The restoration efficiency value of the node in the network simulation model of the power grid to be identified; based on the restoration efficiency value of the node in the network simulation model of the power grid to be identified, simulate and remove the node in the network simulation model of the power grid to be identified to obtain the power grid to be identified. The removal cost value of the node in the network simulation model for identifying the power grid; wherein, the removal cost value is used to represent the removal cost that needs to be considered when removing the node in the network simulation model of the power grid to be identified; based on the power grid to be identified The removal cost value of the node in the network simulation model of the grid is obtained, and the target node in the network simulation model of the power grid to be identified is obtained. The technical problem that the existing identification method cannot accurately identify the most important target removal node of the power grid is solved.
Description
technical field [0001] The present application relates to the field of complex network analysis, and in particular, to a method, apparatus, device and storage medium for identifying a target node of a power grid. Background technique [0002] Removal resistance research methods of complex networks are mainly based on important node identification methods in complex networks, but the current identification methods for target removal nodes in power grids usually focus on conceptual theory and qualitative analysis, so the most important targets of the power grid cannot be accurately identified. Remove nodes. SUMMARY OF THE INVENTION [0003] The main purpose of the present application is to provide a method, device, device and storage medium for analyzing vulnerable points of a power grid, aiming to solve the technical problem that the existing identification methods cannot accurately identify the most important target removal node of the power grid. [0004] In order to ach...
