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

Update to system strength constraints in North Queensland

AEMO ELECTRICITY MARKET NOTICE

Refer to market notice 110677

AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
Due to commissioning of new feeder 8905 (H13 Ross - H39 Woree) 275kV line in Far North Queensland, the system normal system strength equations for low North Queensland demands and all Karreya stations out of service conditions have been revised.

A revision to the constraint equations will be implemented at 1400 hrs on Tuesday 20th February 2024.

The new system strength combinations have now published in a limits advice document on AEMO's website. For more information refer to the new limits advice: https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/system-operations/congestion-information-resource/limits-advice

This advice contains all the combinations for Queensland for system normal cases.

Below constraint equations in the Q-NIL set will be modified:

- Q_NIL_STRGTH_KBWF
- Q_NIL_STRGTH_KBWF_I
- Q_NIL_STRGTH_HAUSF
- Q_NIL_STRGTH_HAUSF_I
- Q_NIL_STRGTH_MEWF
- Q_NIL_STRGTH_MEWF_I
