Today’s LiveWire Spotlight examines the initial posting of a technical guidance document describing the best approaches to deploying wind and solar farms to locations where the transmission system is sparsely populated (a weak system).   The guideline shows how weak systems can be detected and offers solutions to reduce potential instabilities; e.g.; add interconnections; install lower impedance transformers; deploy synchronous condensers; decrease resource output.

Draft 1 of NERC’s Reliability Guideline on Integrating Inverter-Based Resources into Weak Power Systems has been posted for a 45-day stakeholder review.  Comments must be returned to reliabilityguidelinecomments@nerc.net by August 25, 2017.
