Application prospect and key technologies of digital twin technology in the integrated port energy system

Introduction: The structure of green and low-carbon ports is complex, and an integrated port energy system with complex characteristics such as multi-energy flow coupling and information physical fusion has been formed.Methods: Digital twin technology provides a new solution for the perception, analysis, and optimization of integrated port energy system. The paper explores the digital twin of integrated port energy system. Based on the development trend and function of integrated port energy system, the digital twin of integrated port energy system architecture is proposed to explore its potential application services. Specifically, considering the functions and structural characteristics of the port, the digital space of integrated port energy system 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 integrated port energy system from the physical and data dimensions. The hybrid driving method based on data and mechanism is used to explore digital twin of integrated port energy system and find potential better applications.Results and discussion: Finally, combined with the current development needs of integrated port energy system, this paper analyzes the key problems and technologies that need to be broken through in the specific implementation of digital twin of integrated port energy system, 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 ".
