Updated NSW system normal voltage stability limit
AEMO ELECTRICITY MARKET NOTICE
Refer to market notice 105936?
The Murraylink Very Fast Runback (VFRB) scheme was modified to increase the capacity of the network due to the increase in generation in the area. The scheme was changed so Murraylink VFRB could be activated / de-activated depending on the time of day on the monitored 220kV lines in north-west Victoria.?
Transgrid has advised AEMO on a revision to the X5 voltage collapse limit with this change to VFRB. This will now be managed by two limits.?
The following constraint equation changes will be implemented at 0900 hrs on Thursday 16th March 2023:
N^^N_NIL_X5_BEKG (replaces N^^N_NIL_3)
N^^N_NIL_X5_BESH (new)?
For full details on the factors on constraint equations and all the constraint equation changes - these have now been loaded into AEMO's pre-production systems.?
