EMT simulation models for large-scale system impact studies in power systems with high IBR penetration

Thu, Apr 20, 2023 10:00 PM - 11:45 PM CEST
This webinar summarises the work done in CIGRE WG C4.56 which subsequently published in the Technical Brochure 881. It discusses detailed and systematic whole-system power system modelling based on electromagnetic transient (EMT) simulation for large power systems with a high penetration of inverter-based resources (IBR) where the conventional phasor-domain simulation tools may fall short.
The level of details to be included in an IBR EMT model to make it suitable for wide-area system impact studies is then discussed. Approaches for systematic development and testing of the whole-system EMT models is also discussed.
Lastly, it presents several practical case studies on how these wide-area EMT models have been used across the world and the insight provided by them which could not have been otherwise provided by conventional phasor-domain models.
