Today’s LiveWire Spotlight examines a draft NERC Reliability Guideline on the DER_A model, which represents distributed energy resources in dynamic stability studies.  The latest version captures the parameter updates driven by the adoption of IEEE 1547-2018 and California Rule 21 – and discovered in EPRI and WECC studies after the original guideline was released.  

The updated version of NERC’s Reliability Guideline on the Parameterization of the DER_A Model has been posted for a 45-day stakeholder review.  Comments must be returned to John.Skeath@nerc.net and Stephen.Crutchfield@nerc.net by August 13, 2022.
