Update to System strength requirements in North Queensland
AEMO ELECTRICITY MARKET NOTICE
Refer to market notice 93841
AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
Due to reduced numbers of Gladstone units online, the system normal equations have been revised to include below combination.
-If Stanwell >=2, Stanwell + Calllide >=3, Gladstone >= 1, Stanwell + Callide + Gladstone >= 7, Kareeya >=2, Haughton Syncon status = ON, North Queensland load >=250 MW,
Ross+FNQ load >=100 MW, limit Mt Emerald Windfarm to 80% and no limit to other solar farms.
A revision to the constraint equations will be implemented at 1100 hrs on Tuesday 16th August 2022.
The new combinations will be published in a limits advice document on AEMO's website on Wednesday 17th August 2022.
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 of the form below will be modified:
Q_NIL_STRGTH_CLRSF
Q_NIL_STRGTH_COLSF
Q_NIL_STRGTH_DAYSF
Q_NIL_STRGTH_HAMSF
Q_NIL_STRGTH_HAUSF
Q_NIL_STRGTH_HAYSF

Update to SA to Victoria limits for Para SVC outage
AEMO ELECTRICITY MARKET NOTICE
AEMO has been working with ElectraNet on a review of the oscillatory stability limits for the Para SVC outage for flows from South Australia to Victoria.
From that review the these limits from SA to Vic have been increased by 50 MW. The limit on Heywood has changed to 470 MW and for Heywood + Murraylink to 620 MW when the oscillatory stability monitoring is in service. If oscillatory monitoring is not in service the 50 MW increase will not apply.
The revised constraints were implemented in the constraint set S-PA_VC1 at 1300 hrs Friday 24th June 2022:
S:VS_PASVC_570OSC_AT
S:VS_PA_SVC_620
S:V_PASVC_420OSC_AT
S:V_PA_SVC_470
SV_470_DYN
AEMO and ElectraNet are continuing their studies on the limits for the Para SVC outage to determine if further increases can be made.
For further details on this this change please contact ben.blake@aemo.com.au
