Breaking down the pattern of mutual separation between different energy systems and realizing the integration and coordination of multi-energy system(MES)is an effective way to solve the problem of renewable energy accommodation. Firstly

the research framework of the MES theory and method towards renewable energy accommodation is put forward. On the basis of the research mentioned above

the existing researches are reviewed and corresponding thinking is proposed from the perspectives of basic modeling

operation optimization and system planning. Next

the existing researches are categorized into two typical research objects which are the electric-thermal coupling distract MES and the electric-gas coupling cross-regional MES. The related key points of the research on MES towards renewable energy accommodation are reviewed and commented. Finally

the key scientific problems towards the renewable energy accommodation are summarized and the future directions of the research on MES is prospected.
