Update to system strength requirements in North Queensland
Refer to market notice 106175
AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
Due to commissioning of Clarke Creek wind farm in Far North Queensland, the system normal equations have been revised.
A revision to the constraint equations will be implemented at 1100 hrs on Monday 9th December 2024.
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_KBWF
-Q_NIL_STRGTH_MEWF
Two new equations have been added:
-Q_NIL_STRGTH_CKWF
