乡村振兴战略下农网综合效益评价模型研究

Research on the Comprehensive Benefit Evaluation Model of Rural Power Grid Under Rural Revitalization Strategy

农村地区之间存在着显著的地区差异,为了指导农村电网投资,提出一种基于组合赋权和多属性边界逼近区域比较法(multi-attributive border approximation area comparison,MABAC)的差异化农网综合效益评价模型。首先,综合考虑农村地区差异及乡村振兴战略对农网发展的要求,从农网投资经济效益、供电能力、基础设施情况、地区发展带动、生产生活质量、清洁低碳发展等6个方面构建农网综合效益评价指标体系;其次,基于最小化主客观权重异质性原则构建基于图模型—熵权法的组合赋权模型,并引入MABAC方法用于解决农网综合效益评价问题;最后,通过算例分析验证了所提出模型的有效性。

There are significant regional differences among rural areas.In order to guide rural power grid investment,a differentiated comprehensive evaluation model of rural power grid investment benefits is proposed based on combination weighting and multi-attributive border approximation area comparison method.Firstly,considering the differences between rural areas and the requirements of the rural revitalization strategy for the development of rural power grid,a comprehensive benefit evaluation index system of rural power grid is constructed from six aspects:economic benefits of rural power grid investment,power supply capacity,infrastructure,regional development drive,production and living quality,and clean and low-carbon development.Secondly,based on the principle of minimizing the heterogeneity of subjective and objective weights,a combined weighting model based on the graph model entropy weight method is built,MABAC method is introduced to solve the problem of comprehensive benefit evaluation of rural power grid.Finally,the validity of the proposed model is verified by the example analysis.
