Update to system normal constraint equation in NSW for transient voltage stability in south-west NSW

AEMO ELECTRICITY MARKET NOTICE

Refer to market notice 92840.

Transgrid has advised AEMO of an update to the transient voltage stability limit in south-west NSW for loss of Darlington Point to Wagga (63) 330 kV line. The limit will include terms for the Darlington Point and Riverina BESS.

The following constraint equation will be updated with the above changes at 1100 hrs Friday 20th September 2024.
N::N_NIL_63

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

For further details on these constraint equation please contact ben.blake@aemo.com.au
