95690CONSTRAINTS01/04/2022 09:00:20 AM
Update to Vic to NSW transient stability limit
AEMO ELECTRICITY MARKET NOTICE
AEMO has completed a comprehensive review of the system normal transient stability limit for loss of a Hazelwood to South Morang 500 kV line for flows from Victoria to New South Wales. The revised limit takes into account a larger range of inertias, demands, interconnector flows and many different plants online. The revised limit is generally lower than the existing limit due to lower demands and inertias in the Victorian system since the last review back in 2016. However, it is expected the revised limit will normally be under-cut by the Victorian export voltage collapse limit for loss of all APD potlines.
The revised constraint equation includes generators in southern NSW and generation in Victoria on the left-hand side as well as interconnectors. Full details on the limits advice are to be published on 04/04/2022 on the AEMO website: https://aemo.com.au/energy-systems/electricity/national-electricity-market-nem/system-operations/congestion-information-resource/limits-advice
This revised limit will be implemented to the Victorian system normal constraint set V-NIL at 1000 hrs Tuesday 5th April 2022, with the following changes:
Constraint equations to remove:
- V::N_NIL_V
- V::N_NIL_S
- V::N_NIL_Q1
- V::N_NIL_Q2
Constraint equations to add:
- V::N_NIL_V1
- V::N_NIL_V2
- V::N_NIL_O1
- V::N_NIL_O2
These constraint equation changes have already been applied in AEMO's PreProduction systems.
For further details on the constraint equations please contact terry.liu@aemo.com.au
