Today’s LiveWire Spotlight examines a new draft NERC Reliability Guideline on DER_A, the latest generic model representing small distributed energy resources in dynamic stability studies. The subject matter is aimed at planners and operators looking to simulate the impact of distribution-side renewables on electric system voltage and frequency stability.

The initial draft 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 reliabilityguidelinecomments@nerc.net by August 7, 2019.
