Integrated energy system (IES) has broken the boundaries between various terminal energy networks. Comprehensive evaluation of its technology popularization and application is an important step to promote the development and construction of IES. To cope with the problems of IES such as technology's wide scope, large number influencing factors, and complicated evaluation indexes, an evaluation model and method of IES technology's popularization and application are established by combining operation research comprehensive evaluation theory and digital portrait technology. Based on massive monitoring data and IES operation data, the evaluation model generates a multi-source feature evaluation label system regarding to environment, performance, economy and society, and integrates the popularization and application information from many aspects to build a complete and multidimensional IES technology portrait. According to expert scoring and important information feature screening of IES original data, a method combining subjective and objective analytic hierarchy process (AHP-entropy weight method) is used to assign weights to the labels, and the contour of IES technical portrait is formed by fine weight calculation. Finally, the national IES demonstration project in Shanghai Lingang and a park level IES project in the north are selected as examples for evaluation and verification. Results show that the model and method proposed in this paper are applicable in engineering applications and can provide reference for design and construction of IES and promotion and application of key technologies.
