Workshop C4: Generic EMT-Type Modelling of Inverter-Based Resources for Long-Term Planning Studies

Presenters : Jean Mahseredjian (Polytechnique Montréal, Canada), Aboutaleb Haddadi  (EPRI, US)

The dynamics of modern power systems are increasingly shaped by the fast, nonlinear controls of power-electronics-interfaced generation resources and loads. Connecting a new resource to the power system requires preliminary review and comprehensive grid‑impact assessment studies, as well as validation during commissioning. To support these studies, high‑fidelity resource models—including detailed control logic and parameters—must be provided to all involved entities. Electromagnetic transient (EMT) models are increasingly required to capture the detailed behaviour of technologies such as wind turbines (WTs), solar photovoltaic (PV) plants, battery energy storage systems (BESS), flexible AC-transmission system devices, and high-voltage direct current (HVDC) converters. This workshop focuses on the role of generic EMT-type models of inverter-based resources (IBRs) to facilitate long-term planning studies in the absence of site-specific OEM models.
