In this paper,the multi-functional coupling system is taken as the basic object,focusing on the economic evaluation of the multi-functional coupling system,and a feasible evaluation scheme is put forward to realize the comprehensive life-cycle evaluation of the multi-functional coupling system. It is divided into three parts. Firstly,the integrated scheme of multi-energy coupling system is summarized in general. On this basis, the net profit of life cycle is taken as the core objective to improve the absorp. tion capacity of wind power,and the system constraints are summarized. Based on the above contents, the mathematical model of economic evaluation is obtained. At the same time,the analysis of net profit of multi-energy coupling system is carried out. Finally,the actual wind farm and coal chemical enterpris. es are introduced,and the economic analysis is carried out based on the evaluation model proposed above.
