In order to improve the energy efficiency,integrated energy systems(i.e.integrated electricity-heat-gas systems)attract increasing attention worldwide in recent years.Efficient and accurate multi-time-scale dynamic time-domain simulations play an essential role in the operation and control of the integrated energy system.Taking the dynamic modeling and simulation of the integrated energy system as the research object,the structure and dynamic process of integrated energy system is presented first in this paper.Then,this paper introduces the research progress achieved in the dynamic modeling and simulation technology of integrated energy system from three key points of basic model,simulation technology and numerical calculation,mainly including multi-energy coupling general modeling theory,partitioned multi-rate simulation technology,and efficient numerical calculation implementation method for heterogeneous energy networks.On this basis,the key challenges that still need to be solved in the existing research are discussed,such as dynamic modeling under variable operating conditions,multi-rate partitioning interface processing,and selection of numerical solution formats.Finally,the research directions and application scenarios of key dynamic modeling and simulation techniques for the future integrated energy system are prospected.
