New system normal constraints to manage Murraylink real time dynamic rating

AEMO and APA have been working on better ways to reflect Murraylink transfer capability more accurately during high ambient temperature conditions. APA has supplied AEMO with a real time dynamic rating and AEMO will apply this in new constraint equations to dispatch Murraylink.

At this stage, the constraint equations will only be active in Dispatch timeframe.

The following two constraint equations will be implemented in constraint set V-NIL and S-NIL, at 1000 hrs on Thursday 12th March 2026:

VSML_RAT_LIM_DYN
SVML_RAT_LIM_DYN

For full details on the formulation, the new constraint equations have now been loaded into AEMO's pre-production systems.
