Today’s LiveWire Spotlight examines a joint NERC-WECC effort looking to identify and correct deficiencies in the base cases used to simulate dynamic disturbances in the Western Interconnection.  The need arose from findings following the Blue Cut and Canyon 2 fires outside Los Angeles that inverter-based performance is inadequately modeled by WECC planners.

The NERC-WECC Base Case Review exposes a major flaw in the use of monetary sanctions to enforce reliability compliance Clients will want to closely follow the steps WECC takes to resolve the coordination issues as they extend well beyond dynamic simulation modeling.
