The techno-economic evaluation of school integrated energy system based on G1-anti-entropy weight-TOPSIS method

Abstract

Abstract Scientific and reasonable evaluation system and method of technical economy are helpful to improve the technical economy of integrated energy system (IES). This paper analyzes the energy flow of the school integrated energy system (SIES), and constructs the techno-economic evaluation index system of the SIES from three aspects: technology, economy and environment. The evaluation index includes qualitative analysis index and quantitative analysis index. The techno-economic evaluation model of the SIES based on the G1-anti-entropy weight-TOPSIS method is constructed. The evaluation model reflects the subjectivity and objectivity of evaluation. It also overcomes the problem that the AHP method needs consistency test and high sensitivity of entropy weight method leads to the failure of index. Finally, a case study is conducted on a school in northeast China. The results of the analysis verify the feasibility of the evaluation index system and evaluation method. The evaluation system and evaluation method proposed in this paper can provide reference for the selection of SIES construction and operation plan.
