The low-carbon integrated energy system is a multi-energy system that integrates multiple low-carbon tech-nologies and measures,fully mobilizes flexible resources in the energy system,promotes clean energy accommodation and reduces carbon emissions,and is a physical carrier to achieve the goal of carbon peaking and carbon neutrality.Firstly,this paper demonstrates the low-carbon integrated energy system as a practical path for an energy transition from the per-spectives of macro strategy,physical carrier,and low-carbon technology.This paper summarizes the definition and characteristics connotation of the low-carbon integrated energy system.Then,a low-carbon research framework is estab-lished,and the carbon reduction potential of the low-carbon integrated energy system is explored from the source-grid-load-storage and carbon capture technology.To fully mobilize the low-carbon potential of the low-carbon in-tegrated energy system,several key issues of the low-carbon integrated energy system are extracted and summarized from aspects of cooperative planning,optimal scheduling,and low-carbon market mechanism.Finally,focusing on these col-laborative optimization key issues,this paper elaborates the low-carbon integrated energy system development from the viewpoint of research status,challenges,and research prospect so as to provide a reference for the low-carbon develop-ment of energy systems.
