摘　　要：智能电网包含不同的发电模式,本身具有复杂性、智能性等特点,对智能电网的综合效益进行评价具有一定的现实意义。本文从环境效益、经济效益、社会效益、安全性四个方面,建立了综合评价指标体系。根据Vague集(软集)原理,建立Vague集决策矩阵,利用记分函数和指标的确信度来构建各证据下的不同方案的Mass函数,然后运用D-S合成法则进行信息融合,从而得出综合评估结果。选用我国某智能电网进行案例分析,验证了本文提出的评价指标和模型的科学性和实用性。With different generator models, smart grid has the characteristics of complexity and intelligence; therefore, the comprehensive benefits evaluation of smart grid is practically significant. This paper establishes the comprehensive evaluation index system from four aspects： security, economic, social and environmental benefits. Formulate a vague decision matrix based on vague set; construct mass function for different evidences and schemes on the basis of scoring function and indicator reliability; fuse information by using D-S evidence theory; finally obtain the comprehensive evaluation result. The case study of a smart grid in China has verified that the proposed evaluation indexes and model are scientific and practical.
