110678CONSTRAINTS02/11/2023 12:08:31 PM
Updated Victorian system normal voltage oscillation limit
AEMO ELECTRICITY MARKET NOTICE
AEMO has completed a comprehensive review on voltage oscillation issue in south-west Victoria with consideration of wider asynchronous generators in the area. The voltage oscillation occurs in the south-west region when Heywood interconnector flow is higher than 500 MW from South Australia to Victoria.
The limit will manage the total MW output from Stockyard Hill, Dundonnell and Macarthur wind farms during period when flow on Heywood interconnector higher than 500 MW towards Victoria.
The new constraint equation includes asynchronous generators in south-west Victoria on the left-hand side. This limit is to replace the existing south-west Victoria voltage oscillation limit. Full details on the limits advice are to be published shortly on the AEMO website: https://aemo.com.au/energy-systems/electricity/national-electricity-market-nem/system-operations/congestion-information-resource/limits-advice
The following changes will be implemented at 1000 hrs on Friday 3rd November 2023
? Constraint equation will be removed from constraint set V-NIL:
V_SHWF_FLT_286
? Constraint equation will be implemented and added to constraint set V-NIL:
V_SH_DD_MAC_FLT_965
For full details on the formulation, the new constraint equation has now been loaded into AEMO's pre-production systems.
For further details on this change please contact terry.liu@aemo.com.au

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
