| description | Over the past decade, the growth of new power plants has become a trend, with new energy stations growing particularly fast. In order to solve the problem of electricity consumption, the development of hybrid pumped storage based on hydropower stations has become a focus, so it is necessary to evaluate and analyze its technical and economic characteristics. Based on the characteristics of pumped-storage power stations, this paper proposes a comprehensive benefit evaluation model for the functional, financial, and environmental benefits. The model uses the fuzzy Delphi method to improve the rank correlation analysis method and introduces the entropy weighting method, calculating the comprehensive weight of indicators by the subjective and objective combination weighting method. The fuzzy comprehensive evaluation method is used to establish a comprehensive evaluation model and calculate the comprehensive benefit evaluation grade of hybrid pumped-storage power plants. Finally, the practicality and validity of the evaluation model are verified through case studies, and the technical and economic characteristics and superiority of the hybrid pumped-storage power plants are analyzed based on the evaluation results. |
