Constraint invoked to manage power system security in SA region
AEMO ELECTRICITY MARKET NOTICE
Refer to market notices 58785
Constraint Invocation to manage power system security in SA Region
In order to maintain sufficient fault levels in SA and hence a secure operating state, the following constraint set was invoked at 1500hrs which operates in both Dispatch and Pre-Dispatch:
S_WIND_1200_AUTO
This constraint equation automates the process of applying the 1200 MW limit on the wind farms. If there is enough synchronous generation online it will be "swamped" out by adding 10000 to the right-hand side, otherwise the 1200 MW limit will be applied.
