Description: This System Change Request (SCR) incorporates Direct Current Tie (DC Tie) scheduled ramp into Security-Constrained Economic Dispatch (SCED) by updating the formula used by the Resource Limit Calculator (RLC) to calculate the Generation To Be Dispatched (GTBD) value to include the addition of a scheduled 5-minute DC Tie ramp rate (DCTRR). This DCTRR will be calculated from the scheduled system-wide DC Tie ramp times five and a configurable factor to capture the scheduled 5-minute DC Tie ramp.
Reason: Market efficiencies or enhancements
