Title: Brief Review of Blackouts on Electric Power Grids in Viewpoint of Complex Networks
Abstract: In this paper,a brief review of blackouts on electric power grids is given.Firstly,we sum up the holistic topological characters of electric power grids,including their small-world effects,exponential degree distributions,power-law load distributions,and robustness intervenient between possian and scale-free networks.And then,we investigate the self-organized criticality in electric transition dynamics,and suggest a new measure,the time length of power shortage,to estimate the size of blackouts.The empirical results strongly support the recent theoretical hypothesis of the existence of self-organized critical behaviors.Finally,we put forward some unsolved problems and discuss how to statistically reduce the size of blackouts.
