基于博弈论组合赋权的农村电网综合评价体系研究

Research on rural power system comprehensive evaluation system based on game theory combination weights

随着农村电网升级改造的深入和农村居民生活水平的不断提升,农村电网的电网结构、运行水平、负荷种类和负荷运行特征都已经发生了明显的变化,传统农村电网综合评价指标体系和评价方法已不能满足当前农村电网的需求。该文提出一种计及分布式电源接入和负荷运行特性的农村电网综合评价体系。首先构建涵盖源-网-荷等反应农村电网结构和运行特点的综合评价指标体系,然后对现有的单一农村电网评价方法进行全面梳理,提出基于博弈论的组合赋权法,并进行层次化指标的权重计算,为体现评价体系的适应性,选择中国不同地区农村电网进行横向对比,以验证算法的有效性。在乡村振兴的国家战略背景下,该文提出的农村电网综合评价体系具有较强的实用性,能够为农村电网的投资提供参考依据。

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 source-grid-load 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.
