为全面深入分析省级层面建设新型电力负荷管理系统的综合效益，开展了对新型电力负荷管理系统综合评价体系的研究。首先，构建了考虑技术、社会、环境、经济效益的评价指标体系；其次，通过改进层次分析法对综合效益的主观权重进行确定，考虑到指标体系既有定性指标也有定量指标，基于直觉模糊数概念确定客观权重，通过合作博弈理论确定综合权重；最后，引入垂面距离的概念对传统逼近理想解排序（technique for order preference by similarity to an ideal solution, TOPSIS）方法进行改进，增强了评价结果的精准度。通过应用所提评价体系对不同省份的新型电力负荷管理系统的建设情况进行评价，结果表明：所研究的体系在对新型电力负荷管理系统建设的综合效益及多维度效益评价的过程中，表现出较强的系统性、科学性、精准性及可行性。

To comprehensively and deeply analyze the overall benefits of provincial-level construction of new type of power load management system, a study on the comprehensive evaluation system for such systems was conducted. Firstly, an evaluation index system that considers technical, social, environmental, and economic benefits was established. Secondly, the subjective weights of the comprehensive benefits were determined through an improved analytic hierarchy process. Given that the index system encompasses both qualitative and quantitative indicators, the objective weights were determined based on the concept of intuitionistic fuzzy numbers, and the comprehensive weights were determined through cooperative game theory. Finally, the concept of perpendicular distance was introduced to enhance the traditional technique for order preference by similarity to ideal solution (TOPSIS) method, thereby improving the accuracy of the evaluation results. By applying the proposed evaluation system to evaluate the construction of new power load management systems in different provinces, the results show that the studied system exhibits strong systematicity, scientificity, accuracy, and feasibility in the comprehensive and multidimensional benefit evaluation of the construction of new power load management systems.
