Building multiple energy systems which bring together the electric power system, heat system and natural gas system in order to coordinate the whole system in the processes of generation, transmission and consumption, is a necessary road to energy internet. By co-optimizing and fully utilizing the synergy of the multiple energy system (MES), the overall efficiency of the energy utilization will be promoted and the cost of the energy will be brought down. Energy hub (EH) is an important and handful approach for modeling the multiple energy systems. It has received considerable attention worldwide since it was proposed. In this paper, the basic concept of EH and its modelling methods were firstly introduced. The operation and planning optimization models and solution algorithms were then reviewed. EH models for typical integrated energy systems were illustrated. Finally, the key issues of EH research were summarized and the potential research topics on EH were proposed.
