| The investment decision evaluation on PV projects features multiple criteria,and involves various factors in economy,technology,society,environment,policy and other aspects.The purpose of research in this paper is how to provide opinions for decision makers in making decisions when facing the optimization issue of PV projects.So this paper introduces the multiple criteria decision making(MCDM)to solve this issue.The main work contents of this paper are as follows:First,as per the selection principle of evaluation indicators,this paper preliminarily obtains the set of proposed indicators for investment decision evaluation for PV projects,and innovatively introduces the grid connection indicator and urgency degree indicator based on the actual investment decisions of grid enterprises;establishes the selection flow and adjustment rules for evaluation indicators in view of the indicators to be selected,chooses and determines 16 secondary indicators as per the judgment on indicator selection rules,and finally obtains the investment decision evaluation indicator system for PV projects.Second,this paper interprets and quantifies each evaluation indicator,and establishes corresponding grading rules;then considers the absolute preference of decision makers and absolute limitations of actual conditions based on the application of traditional ELECTRE Ⅲ method,and proposes the concepts of "absolute superior threshold value" and "absolute negative threshold",enabling the investment decision evaluation on PV projects to further comply with the actual situation,and optimizing and improving the evaluation model to a certain extent.Finally,this paper takes 4 PV projects in Zhejiang,Hunan,Xinjiang and Inner Mongolia as examples,assesses the investment decision evaluation models for PV projects based on ELECTRE Ⅲ method,and analyzes the final model assessment results,so as to verify the feasibility of model in assisting the projects in conducting investment decision evaluation. |
