Analysis and Comparison on Several Kinds of Models of Cascading Failure in Power System

Highly interconnected power grid is developing more and more complex. Cascading failure in such complex power grid, which can be triggered by some disturbances, will have global catastrophic effects over the entire networks. So the research on cascading failure of complex power grid is of significant concern. The foundation of such research is the modeling. In this paper, the mechanism of cascading failure in power grid is firstly explained. Then respectively from the point of view in artificial power system and complex network, several existing models are introduced and commented. And some feasible methods, which should be paid more attention to in the future, in order to prevent and control cascading failure are also analyzed and discussed
