Priority ordering of power grid emergency repair task based on algorithms ofgroup AHP and TOPSIS

Abstract

An improved algorithm of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS)is put forward to optimize power grid emergency scheduling. Based on TOPSIS algorithm, the expert decision-making weight coefficients are worked out by group analysis. Then the weights of target attributes of grid are set according to Group Analytic Hierarchy Process (AHP), which not only embodies experts’ experience-based judgment but is more objective and reliable to improve the accuracy of the priority order of task. In the simulation analysis, the improved TOPSIS method is applied to get the priority order for urgent repair in power grid accident. The result is identical to the real situation so to have verified the feasibility of this method.
