Today’s LiveWire Spotlight article examines the initial version of a NERC Application Guide describing computer modeling that most accurately represents synchronous and inverter-based resources. The support document primarily addresses three scenarios where simulations using validated turbine-governor and inverter frequency control models do not match the observed results from actual events.

The initial draft of NERC’s Application Guide for Turbine-Governor Modeling has been posted for a 45-day review and commentary period. Feedback must be returned to reliabilityguidelinecomments@nerc.net by April 26, 2019.
