Abstract :
The concept of state transition graph is used to analyze the cascading failure of electrical power grids in different load level. State transition graph is introduced first, then the state transition model of electrical power system DC flow is designed. The IEEE 9-bus sample system is used to show the state transition graph evolution by aggravating the load level. Some general conclusion is drawn by this method.
