【 摘 要 】

The construction of integrated energy system contributes to the large-scale development of renewable energy and improves the flexibility and safety of social energy supply. However, the current integrated energy system project benefit evaluation index system is still not perfect, lacking the standard and can hardly be applied to the actual project evaluation. In view of these problems, this paper constructs a universally applicable integrated energy system project benefit evaluation index system named '3E1F', evaluating benefits from four aspects which are energy efficiency, economic benefit, environment benefit and function benefit. The index weight is established by the combination of AHP-entropy weight method. The effectiveness and feasibility of the benefit evaluation index system and calculation method are verified by actual cases. Finally, combined with the actual cases and the main problems of the current integrated energy system project construction, this paper puts forward several optimization suggestions for improving the efficiency of the integrated energy system project.
