Because the present Fuzzy Comprehensive Evaluation (FCE) of distribution network has the characteristics of single evaluation, ignoring the randomness and fuzziness of the index data of the distribution network, a fuzzy comprehensive evaluation of distribution network based on cooperative game theory and trapezoidal cloud model is proposed. The method firstly establishes comprehensive evaluation index system for distribution network. Then it gets the index of constant weight by means of cooperative game method, corrects the constant weight by variable weight formula, and on the basis of fuzzy comprehensive evaluation, the trapezium cloud model instead of membership function, realizes the comprehensive evaluation of distribution network. Finally, taking a city distribution network as an example, the evaluation results are analyzed and the results show that this method is feasible for the comprehensive evaluation of distribution network.
