New system normal constraint equation in Victoria for voltage collapse on trip of Ballarat - Waubra - Ararat line
AEMO ELECTRICITY MARKET NOTICE
In the event of a trip of the Ballarat - Waubra - Ararat 220 kV line the Ararat, Crowlands, Bulgana, Murra Warra and Waubra wind farms will be tripped off. AEMO has completed work on a revised voltage collapse limit for this contingency which will replace the existing 600 MW cap on these generators. FCAS constraint equations have also been developed for this contingency.
The energy constraint equation includes generators in south-west NSW and north-west Victoria on the left-hand side as well as VIC1-NSW1.
The following constraint equations will be implemented at 1000 hrs Monday 25th May 2020.
