Power System Large Scale Blackout Emergency Evaluation Index System and Its Application

The evaluation index system for the power system emergency response to large-scale blackouts is proposed.The index system is based on the characteristics of large-scale blackouts,the general theory on emergency response,and the systems theory and methodology.The proposed index system consists of four first-grade indices,twelve second-grade indices and thirty-eight index attributes.Fuzzy analytic hierarchy process is used for the comprehensively quantitative analysis of multiple indices;firstly,the analytic hierarchy process is used to determine the weight of each index,and then fuzzy comprehensive evaluation is applied hierarchically.Finally,an example is given which details the emergency response capability evaluation of a Chinese provincial power grid company with satisfactory analysis results.It proves the effectiveness and practicality of the index system and its comprehensive evaluation method.The study will provide effective reference and decision support for the emergency response to large-scale blackouts in electric power sector.
