Update to system strength constraints in North Queensland
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
