Abstract: The co-simulation algorithm has been widely used in digital twin, multi-physics domain coupling analysis and parallel computing of complex large-scale dynamic systems.Compared with traditional strongly coupled analysis, it has the advantages of modularity, intelligence, non-intrusive and efficient calculation.With the development of intelligent manufacturing and the deep integration of the industrial Internet, data interfaces and computing platforms based on co-simulation algorithms have developed rapidly.Due to the differences in stiffness, accuracy requirements and numerical characteristics of multi-physics domain models, the numerical stability of co-simulation algorithms has always been a bottleneck restricting their application.First, the basic concepts, classification and coupling models of co-simulation algorithms are introduced.Then, the numerical stability issues introduced by interface variable interpolation are discussed respectively, and the co-simulation stabilization techniques, local error analysis and macro-time step control methods are summarized.Next, the application and algorithm platform of co-simulation algorithms in integrated energy systems, dynamic systems and digital twin technology are summarized.Finally, facing the future of efficient and high-stability co-simulation algorithms, the research and application of co-simulation algorithms are summarized and prospected.

Key words: co-simulation algorithm, numerical properties, weak coupling, platform of the algorithm
