Abstract Direction of construction of park-level microgrid is gradually developed from multi-energy complementary system in the aspect of source-to-source to integrated energy system with vertical source-network-load-storage integration. This paper analyzes composition and characteristics of park-level integrated energy system firstly. With regard to influencing factors of economy, reliability, energy consumption and environmental protection, an index evaluation model of park-level integrated energy system for microgrid is established. Based on the method of AHP and improved entropy weight to ensure weight assignment of various indexes, a multi-criterion evaluation system named VIKOR is established. Through analysis of sensibility and comparison, validity and rationality of the method system is verified by computing a park-level integrated energy system as an example.
