    Under delay and impedance mismatch conditions, the conventional ideal transformer method (ITM) suffers from severe instability in distributed real-time co-simulation (DRTCS). To address this issue, an interface algorithm (IA) based on perfect delay compensation (PDC) is proposed, which maintains closed-loop pole locations independent of delay and significantly enhances robustness. The algorithm is developed by modifying the current-type configuration of the ITM, and represents the first application of a perfect delay compensation structure to the grid-converter partition in DRTCS. The effectiveness of the proposed method is verified through MATLAB simulink simulation and DRTCS experiments using Speedgoat and Typhoon HIL. Results show that the proposed approach achieves up to 99.5% accuracy under extreme communication delays of 0.8 s, maintaining stability in operating conditions where the conventional ITM becomes unstable.
