【Abstract】 [Objective] "Coupling" exists widely in nature and is the fundamental physical attribute and primary characteristic of the integrated energy system(IES). Clarifying the coupling mechanism of IES can fully leverage its multienergy complementary advantages and tap into its potential as a "virtual energy storage" for new energy consumption. Current coupling research mainly focuses on qualitative analysis of energy coupling forms, which suffers from issues such as "incompleteness," "unquantified," and "difficult to analyze. " [Methods] This paper reviews the analysis and application of IES coupling from both "qualitative" and "quantitative" dimensions. Firstly, starting from the widely existing coupling phenomena, the basic concept of IES coupling is proposed. Secondly, the current status of qualitative research on heterogeneous energy coupling in terms of its impact on planning and operation is sorted out. Then, in view of the limitations of qualitative analysis of IES coupling, the progress of current quantitative research on IES coupling is summarized from the dimensions of indicators and methods, and the potential of quantitative application of coupling is explored from the three dimensions of time, space and energy grade. [Results] Finally, the future research challenges of IES coupling quantification are expounded around modeling, mechanism and application. [Conclusions] Heterogeneous energy coupling involves multiple key essential issues in IES research, such as multi-time scale analysis, source-grid-load-storage coordination, and energy cascade utilization. Clarifying the coupling characteristics will help clarify the essential laws of IES operation and contribute to the formation of new theoretical achievements and application methods.更多还原
