Evaluation of Power System Black-Start Schemes Based on Improved DEA/AHP Evaluation Model

Abstract

Aiming at multiple attribute in electric power system black start scheme evaluation, the characteristics of the subjective and objective weights are difficult to determine; Entropy weight method can not ensure independence; DEA model can't completely sorted and judgment matrix all of 1 problem may come up, this paper puts forward improved DEA/AHP model. According to the index of evaluation index focus type optimal selection, the worst plan to join the group evaluation schemes for evaluation. This method not only can guarantee the independence of the scheme can achieve full sort again, avoid the process of calculating the weight at the same time, to enhance the objectivity. The method is simple in calculation and reliable results, tianjin power grid black start scheme evaluation results prove the effectiveness of this method.
