The power system complexity and its related research progress are introduced in terms of existence and evolution,and the relationship between existence complexity and evolution complexity is analyzed. The existence complexity contains the muhilayer ＆ inter-relevancy,nonlinear dynamics,randomness, real-time,social economics,openness,etc.,and the evolution complexity contains the self-organization,synergetics, mutagenicity,and fractal dimension,etc. The theoretical framework of power system complexity study is proposed ,including its basic concept,its comprehensive analysis method and system ,the power system self -organized criticality,the power system network features,the simulation and prediction methods of power system cascading failures based on the complexity theory,its comprehensive integration technology,etc. The important topics and future work related to the research of power system complexity are pointed out.
