As an important direction of energy reform, integrated energy system has become the focus of research and attention in today's world. Building an integrated energy system can not only improve energy efficiency, but also bring good environmental benefits At this stage, China has launched many R & D projects related to integrated energy systems, aiming to promote the construction of integrated energy systems. The evaluation of the integrated energy system is directly related to the safe and stable operation of the integrated energy system, and is an indispensable part of building an integrated energy system. In this paper, an integrated energy system is taken as the research object. According to the characteristics of multi-energy flow and multi-coupling in the integrated energy system, the indicator system is constructed according to the two levels of system operation and system equipment. Then use analytic hierarchy process to weight each level of indicators and calculate the value of each indicator, and finally make an overall evaluation of the comprehensive energy system to verify the feasibility of the established indicator system.
