Update to system strength requirements 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 Kaban wind farm in Far North Queensland, the system normal equations have been revised to include following combinations.
-If Stanwell >=2, Stanwell + Calllide >=3, Gladstone >= 1, Stanwell + Callide + Gladstone >= 7, Kareeya >=0, Haughton Syncon status = ON/OFF, North Queensland load >=250 MW,
Ross+FNQ load >=100 MW, limit Kaban Windfarm to 100% (with Haughton Syncon ON), 0% (with Haughton Syncon Syncon OFF) and no limit to other NQLD Plants.
A revision to the constraint equations will be implemented at 1400 hrs on Wednesday 1st March 2023.
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

Changes to Murraylink Very Fast Runback and constraints in Victoria
AEMO ELECTRICITY MARKET NOTICE
The Murraylink Very Fast Runback (VFRB) scheme is being modified to increase the capacity of the network due to the increase in generation in the area. The scheme will be changed so Murraylink VFRB can be activated / de-activated depending on the time of day on the monitored 220kV lines in north-west Victoria.
The changes to the scheme will be activated and constraint equaiton modified at 1200hrs Monday 20th February 2023. The following system normal constraint equations will be modified:
V^^V_NIL_KGTS
V^^V_NIL_KGTS_2
V>>SML_NIL_7A
V>>SML_NIL_7B
V>>SML_NIL_7C
V>>V_NIL_13
