Integrated energy system (IES) has the characteristics of multi energy coupling and complementarity, which is conducive to improve energy efficiency. Simultaneously, electric vehicle (EV) is conducive to environmental energy conservation and emission reduction to promote sustainable energy development. Firstly, this paper expounds the basic architecture and planning connotation of IES, and describes the research status of IES planning in domestic and overseas. Then, the operation models of various energy supply storage equipment (ESSE) of IES are described. Based on this, the capacity configuration models of various ESSEs are established, and the power flow models of each energy supply system are summarized. In the aspect of EV charging and swapping facilities planning, firstly, various EV load forecasting methods are discussed, thus the current situation of EV charging and swapping facilities planning is classified and discussed. Then, the research status of collaborative planning of EV charging and swapping facilities and grid, the EV charging and swapping facilities planning considering carbon emission are summarized, respectively. Under the above research background, this paper summarizes the research status of EV charging and swapping facilities planning in IES environment in domestic and overseas. Finally, the bottlenecks faced by the planning and development of EV charging and swapping facilities under IES environment are summarized, and the future research direction is prospected.
