Update to system strength requirements in North Queensland
AEMO ELECTRICITY MARKET NOTICE
Refer to market notice 121468
AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
The system normal equations have been revised to remove Gladstone >=1 requirement.
A revision to the constraint equations will be implemented at 1200 hrs on Tuesday 4th February 2025.
The new 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. Additional information has been included in the limit advice to clarify the requirement to disconnect all inverters/turbines under certain system conditions.
The constraint equation in the Q-NIL set of the form below will be modified:
-Q_NIL_STRGTH_xxxx
-Q_NIL_STRGTH_xxxx_I
