This paper introduces a novel methodology for impedance replication in Power Hardware-in-the-Loop (PHIL) setups, which enables accurate and efficient analysis of power system stability. The proposed methodology utilizes impedance measurements obtained from a real device or grid and employs passive equivalent circuit modelling to replicate the impedance characteristics in a real-time simulator. By executing the replicated impedance model on the real-time simulator with PHIL, the amplifiers output is measured and compared with the measured reference impedance to optimize the replication error. The findings of this study emphasize the significance of impedance replication in PHIL for advanced, flexible impedance-based stability investigations. The proposed methodology offers a practical and efficient approach for replicating complex impedance characteristics in real-time simulations, enabling researchers and engineers to thoroughly analyze the stability and performance of power systems and associated devices.enImpedanceOptimizationPHILReplicationStabilitySynthesisTechnology::620: EngineeringConference PaperConference Paper
