Today’s LiveWire Spotlight looks at the latest support document proposed by NERC centering on the validation of planning models for roof-top solar panel aggregations, stand-alone solar/wind farms, and energy storage resources. The Reliability Guideline offers techniques to compare incident recordings against simulations that model utility-scale (U-DER) and retail-scale (R-DER) facilities attached to the low side of the distribution transformer.

Draft 1 of NERC’s Reliability Guideline on the Model Verification of Aggregate DER Models Used in Planning Studies has been posted for a 45-day stakeholder review.  Comments must be returned to reliabilityguidelinecomments@nerc.net by December 17, 2020.
