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
