Update to voltage stability and system strength constraints in North Queensland

AEMO ELECTRICITY MARKET NOTICE


Refer to market notice 102074


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 equations for system strength and voltage stability have been revised.

A revision to the constraint equations will be implemented at 1400 hrs on Thursday 2nd November 2023.

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.

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

? Q_NIL_STRGTH_KBWF
? Q_NIL_STRGTH_KBWF
? Replace Q^NIL_FNQ_MEWF and Q^NIL_FNQ_WRSVC with new equation Q^NIL_FNQ_8905

Update to Victorian system normal constraint equations ID

AEMO ELECTRICITY MARKET NOTICE

AEMO has been conducting major review of thermal constraint equations for preparation of completion of VNI East project. As part of the review, AEMO is going to update the constraint equations IDs to use the new standard format of below (this is the same standard now used in NSW):

V>>[OUTAGE]_[MONITORING ELEMENT]_[CONTINGENCY ELEMENT]

This is to improve the simplicity and readability of a thermal constraint equation ID.

Constraint equations ID in sets V-NIL and V-NIL_BATS_BETS_15M will be updated to the new format on Thursday 23rd March 2023 at 1000 hrs. The previous used constraint equations ID will be included in the Modification field of the constraint equation for reference.

The changes have now been implemented into AEMO's pre-production system.
