Updates to Victorian system normal stability constraint equations
The Victorian system normal constraint equations that determine Victorian export limits based on transient stability and voltage stability at Heywood for Victoria to South Australia flows will be updated to a revised formulation on 25 July 2016 after 1330 hrs. This revised formulation models the effects of higher flows on Victoria to SA on Heywood and the new series capacitors at Black Range.
The changes are to the following constraint equations :
V::N_NIL_V1
V::N_NIL_V2
V::N_NIL_Q1
V::N_NIL_Q2
V::N_NIL_S1
V::N_NIL_S2
V::N_NIL_SD
V^S_HYCP
