Sensitivity Evaluation Model for Line Outage Based on Entropy and Analytic Hierarchy Process

With the development of economy and society, power customers are very sensitive to line blackouts. Therefore, how to dispatch power maintenance resources according to the emergency degree of power outage has become a prominent problem to be solved by power enterprises. In order to analyze the power line outage sensitivity risk by means of effective early-warning analysis, this paper proposes a sensitivity evaluation model for line outage based on three dimensional data of user profile, outage characteristics and user service. Such an evaluation model comprehensively considers the subjective and objective factors by exploiting the combination algorithm of entropy value method with analytic hierarchy process. The sensitivity evaluation model can be used to provide decision support for improving customer service satisfaction and lean management level of power supply enterprises. Both theory and practice show that our evaluation model can be utilized to effectively analyze the sensitivity of line outage.
