New Victorian system normal voltage stability limit
AEMO ELECTRICITY MARKET NOTICE
A new Victorian system normal constraint equation has been implemented on 15 August 2018 at 0825 hrs. This constraint equation is to manage voltage stability for loss of all APD potlines for transfers from Victoria to NSW. This will most likely limit Victoria to NSW flows under light load conditions.
The new constraint equation is :
V^^N_NIL_1
