Aiming at the shortcomings of single weighting method,an evaluation method for pumped-storage power station site selection based on the combination weighting of game theory is proposed.It constructs an evaluation index system for pumped-storage power station site selection from seven aspects of geography,terrain,geology,water source,society,engineering and economy.The improved Analytic Hierarchy Process(AHP)is used to calculate the subjective weights of the evaluation indicators,while the Entropy Weight Method(EWM)is adopted to calculate the objective weights,and then the game theory is introduced for the combination weighting.A comprehensive evaluation model is finally established in combination with the fuzzy comprehensive evaluation method.The proposed method is applied to the comprehensive quantitative evaluation of the preselected site of a pumped-storage power station project in Hubei Province,and the evaluation results show that the index weights derived from the combination weighting method based on game theory not only incorporate the empirical judgments of subjective weighting methods,but also optimize the data analysis of objective weighting methods,thereby improve the accuracy of evaluation index weights,which has a certain guiding role in the site selection of pumped-storage power station.
