数字孪生支撑下综合能源系统的智慧运维发展与挑战OA

Digital twin technology can deeply integrate the energy system and achieve comprehensive simulation and analysis of all elements,all components,all working conditions and all processes of the integrated energy system.This paper firstly introduces the concept of digital twin technology,the demand of integrated energy system operation and maintenance,and the digital twin technology system,as well as further reviews and analyses the theoretical status quo and technological progress of the integrated energy system from the key technologies supporting the construction of the simulation platform such as modeling method,topology identification,simulation solution,etc.,so as to summarize the different functions of the digital twin platform such as the on-line simulation platform,the operation optimization strategy,and the study of equipment faults.In addition,a digital twin platform framework with virtual-real interaction is constructed.Finally,the challenges encountered in the research and application of digital twin technology in integrated energy systems are presented.
