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.
