A Method for Detecting Vulnerability of Large-scale Power Grid Based On Complex Network

The invention discloses a large-scale power grid vulnerability monitoring method based on a complex network, which comprises the following steps of: establishing a power grid topological model, simplifying the model, analyzing the model, monitoring the vulnerability of the model and evaluating and processing the monitoring result; based on the complex network theory, the power grid topological model created by this invention can improve the evaluation capability of the model, represent the structural characteristics of the power grid through a group of model, draw a node degree distribution diagram and a median distribution diagram of the selected power grid through an artificial intelligence processing module in a graph module, enable the power grid topological model information and characteristic parameters to be easy to analyze and calculate through simplifying the topological model with low requirements on calculation performance, simultaneously, use four attack modes to attack the power grid model, which makes the monitoring data more comprehensive, ensures the monitoring accuracy of power grid vulnerability to a certain extent, realizes the reasonable quantification of electrical dynamic characteristics and static mechanism vulnerability response, and effectively monitors the vulnerable links in the power grid. -1/1 Establishment of Power Grid Topological Model Simplification of Power Grid Topological Model Analysis of Power Grid Topological Model Vulnerability Monitoring of Power Grid Topological Model Evaluation and Treatment of Monitoring Results Figure 1
