Digital twin technology provides a new solution for the perception, analysis and optimization of integrated port energy system. Our paper explores the digital twin of IPES, i.e., IPES-DT. Based on the development trend and function of IPES, the IPES-DT architecture is proposed to explore its potential application services. Specifically, considering the functions and structural characteristics of the port, the digital space of IPES is established, which describes the pan electrification, multi energy flow fusion, the "physics-information-value" coupling, and the characteristics of system operation under uncertain scenarios of IPES from the physical and data dimensions. The hybrid driving method based on data and mechanism is used to explore IPES-DT and find potential better applications. Finally, combined with the current development needs of IPES, this paper analyzes the key problems and technologies that need to be broken through in the specific implementation of IPES-DT, with a view to providing some thoughts and references for the low-carbon development of ports and the future application of digital twin technology under the goal of "double carbon".
