The Research on Brittleness Simulation of Electric Grid Systems Based on Chart Theory

Brittleness source identification is the work of finding every brittle source. The key of analysis of the brittleness of system is to build the brittle model. The chart theory can describe the direction and weigh of the brittle spread model. In this paper, bring forward the method and step of building the brittle model based on the chart theory, build a model of 7 nodes electric power system and analyze it and then obtain the hierarchy electric power system brittle model and the brittle source, and at last verify this method is valid to network system.
