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

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.
