IBR performance issues and modeling deficiencies have been documented in the NERC alerts from 2023 to 2025. NERC disturbance reports have also found that the existing models are unable to reproduce the IBR behaviors during the reported events. The authors have reproduced a local voltage oscillation event in a high IBR-penetration area by modeling the local transmission system and IBRs in electromagnetic transients (EMT) domain. The work highlights the criticality of metering delay representation and modeling the discrete nature of the power plant controllers in reproducing and predicting stability. The work shows that representing the metering delay as the first order lag function, which is the most common representation in standard library models used in the western interconnection of the US, was inadequate, causing blind spots in reliability studies.
