Comprehensive Benefit Evaluation And Analysis Of Replacing Coal By Electricity Technology In Rural Areas

With the continuous and rapid development of national economy,unreasonable traditional energy mining methods and energy consumption structural contradictions are prominent.A series of problems such as energy crisis,environmental pollution,frequent haze and so on are seriously affecting people's production and life.As a secondary clean energy,electric energy has become the best substitute of traditional fossil fuel with the advantages of cleanness,safety and convenience.In response to the call of national "energy conservation and consumption reduction",the State Grid first proposed a new development idea of "electricity comes from far away,clean electricity".The technology of replacing coal by electricity has been vigorously promoted.Through the way of replacing coal by electricity,the utilization rate of energy has been greatly improved,so as to achieve energy conservation and emission reduction.However,the innovation of energy technology will affect the interests of all parties.How to effectively coordinate and achieve the balance of interests has become an urgent problem to be solved in the promotion of coal power generation technology.This paper focuses on the promotion and application of coal electricity technology in rural areas of China.Based on the investigation and collation of the development status of coal electricity technology at home and abroad,the paper analyzes the promotion of coal electricity technology at the level of energy and technology application,and points out the necessity of coal electricity technology promotion and the comprehensive benefit evaluation of economic,environmental and social aspects of coal electricity technology promotion.In this paper,the combination weight analysis method based on the analytic hierarchy process(APH)and entropy weight method is proposed,and the combination weight evaluation process and evaluation index construction method are introduced.Based on the above combined weight analysis method,this paper constructs the economic benefit index,environmental benefit index,social benefit index and comprehensive benefit evaluation model of the promotion of coal electricity technology in rural areas.The model is used to analyze the example of coal electricity technology promotion in rural areas of Wenshui County,Shanxi Province,and to construct the evaluation indexes of economic,environmental and social benefits of coal electricity technology promotion in rural areas of Wenshui County.According to the method of success degree,this paper points out the completion degree of the comprehensive benefit index of the technology promotion of electricity replacing coal in Wenshui County.The results show that the social benefit index,the economic benefit index and the environmental benefit index are basically successful.Based on the systematic analysis of the hindering factors of the promotion of coal electricity technology in rural areas,this paper constructs the strategic indicators of the promotion of coal electricity technology in rural areas,and makes a detailed analysis of the promotion strategies of coal electricity technology in rural areas of Wenshui County and similar rural areas from four aspects of production factors,supporting enterprises,enterprise strategies and government work.
