Abstract

With the continuous upgrading of rural power grids and rising living standards of rural residents, the power grid structure, operating level, load types and load operating characteristics of rural power grids have undergone significant changes. The traditional rural power grid comprehensive evaluation index system and evaluation methods have been unable to meet the current needs of rural power grids. This paper presents a comprehensive evaluation system for rural power network that takes into account the characteristics of distributed power access and load operation. Firstly, a comprehensive evaluation index system covering the structure and operation characteristics of sourcegridload reaction rural power grids is constructed. Then, the existing evaluation methods of single rural power grids are comprehensively reviewed, and a combinatorial weighting method based on game theory is proposed. In order to reflect the adaptability of the evaluation system, we choose the horizontal contrast between different regions in our country to verify the validity of the algorithm. Under the national strategic background of rural rejuvenation, the comprehensive evaluation system of rural power system proposed in this paper has strong practicality and can provide a reference for rural power grid investment.
