Analysis of Distribution Network Weak Point Localization System Based on Topological Information

The current distribution network vulnerability identification mostly focuses on static topology analysis, ignoring the actual business requirements, configuration and the interactions between nodes at each level, which makes it difficult to cope with the complexity and real-time monitoring requirements. To solve this problem, this paper comprehensively collects topological information of the distribution data network, combines the actual demand and configuration, applies network analysis methods to identify critical nodes and paths, and evaluates the vulnerability of the nodes and paths through algorithms and indexes. And we need to visually output the analysis results to support network security management and optimization decision-making, and improve the operational efficiency and reliability of the distribution network.
