Today’s LiveWire Spotlight examines the Standards Authorization Request (SAR) for Project 2022-04, which sets the groundwork for driving the adoption of electromagnetic transient (EMT) models that best represent high-speed inverter-based resources in planning studies.  The SAR Team proposes a strategy to apply EMT techniques only to sensitive areas and/or wherever the electric system is densely populated with inverter-based resources — which should mitigate costs until the technology matures.

•Draft 1 of the Standards Authorization Request for Project 2022-04: Electromagnetic Transient (EMT) Modeling and its unofficial comment form have been posted for a 30-day review.  Your feedback is due back to the project team by September 13, 2022.
