Abstract:
In the environment of reforming transmission and distribution prices, it is particularly important for the operation and development of power grid enterprises to accurately evaluate the comprehensive value of users’ assets received by the power grid. For this reason, based on double entropy correction index weighting a method to evaluate comprehensive value of user’s assets received by power grid was proposed. Firstly, the related theory about information entropy and relative entropy was briefly introduced. Secondly, to improve the rationality of expert scoring results, based on the relative entropy the experts scoring results to evaluate the importance of evaluation indices were revised. Thirdly, based on generalized entropy the G1 weighting method was modified to relieve the subjective arbitrariness of index weighting meanwhile the importance of experience of the indices was also taken into account. Fourthly, a model to evaluate the comprehensive value of the user’s assets received by power grid was constructed. Finally, taking three different kinds of typical users in a certain province in China for example, the proposed method was utilized to evaluate their comprehensive values. Computing results show that using the proposed method the evaluation results are more reasonable, so it can be used for reference for the operation and development of power grid enterprises.
