Abstract: The work in this article analyses the impact of time-delays on distributed real-time simulation stability and accuracy with respect to different decoupling points as well as the impact of decoupling point selection on system modes. We perform analysis of the system modes and participation matrix of the system and determine suitable points that negligibly modify the system modes to decouple the original system. From this analysis, a non-intrusive delay-based model partitioning method for distributing real-time simulations that exploits the flexibility in the context of selecting decoupling points is developed.
