| Abstract |
The increasing penetration of inverter-based resources(IBRs) has significantly increased the complexity of modern power system, challenging conventional RMS-based analysis tools. As a result, electromagnetic transient(EMT) simulations have become essential for accurately capturing the dynamic characteristics of power systems with high IBR penetration. However, large-scale EMT simulations are computationally demanding, limiting their practical implementation in extensive grid studies. This study proposes an equivalencing technique that transforms RMS-based PSS/E data into an equivalenced model, enabling scalable EMT-based simulations in RTDS and PSCAD/EMTDC environments. The results demonstrate that this approach effectively preserves critical dynamic characteristics while significantly reducing computational complexity, facilitating large-scale transient analysis in high-IBR power systems. |
