Update to Negative Settlement Residue constraint equations
AEMO ELECTRICITY MARKET NOTICE
The final report on the consultation for negative settlement residues was published today. One recommendation from the consultation was to change the negative settlement residue constraint equations to manage the "cycling" issue in the clamping process.
The following constraint equations have now been updated to align with the recommendation:
NRM_NSW1_QLD1
NRM_NSW1_VIC1
NRM_QLD1_NSW1
NRM_SA1_VIC1
NRM_VIC1_NSW1
NRM_VIC1_SA1
For more information on this please refer to the consultation documents which is available here:
