| Abstract: | Complex system theory is the most powerful tool for studying the general reasons of cascading failure in electric power systems,and it is also a popular research issues nowadays.In this paper,the achievements and development in the research on cascading failure in power systems are introduced first.Then according to the analysis of the data in 15 years from NERC,the long-term correlation of large blackouts is pointed out,and based on the statistical results,the property of self-organized criticality(SOC) in power systems and its effect are discussed.Finally,the small-world characteristic of the electric power network and its effect on cascading failure are qualitatively analyzed. |

| Keywords: | power law long-term correlation self-organized criticality small-world network |
