Abstract：Aiming at the problems of imperfect value assessment system,non-uniform measurement method,and lack of systematic project preference in the process of carbon asset development of power grid projects,this paper innovatively constructs a diagnostic model for the carbon asset development value of power grid projects.Firstly,a diagnostic indicator system for the carbon asset development value covering five dimensions(technical,environmental,economic,social and risk)has been constructed,realizing the comprehensive quantification and systematization of the value characteristics;Secondly,the combination of emission factor method,economic measurement method and semantic method is used to establish the value index measurement model for four types of typical projects,namely,extra-high voltage transmission,integrated energy system,new energy generation and power grid technical reform;Next,the set-value iteration-critique combination method is employed to determine the weights of above evaluation indicators,and the fuzzy TOPSIS method is introduced to properly handle the qualitative and quantitative indicators,which realizes the comprehensive assessment and reasonable ranking of carbon asset development projects.Finally,the final ranking of the four types of typical projects was determined to be Integrated Energy System＞Grid Technology Reform＞Extra High Voltage＞New Energy Power Generation.Through the research of the whole chain of'index system-measurement model-comprehensive assessment',the most suitable carbon asset development projects of power grid companies are identified,which provides theoretical methodological support and practical guidance for the value diagnosis and optimal layout of power grid carbon asset development.
