Revised System Strength limits in North Queensland
AEMO ELECTRICITY MARKET NOTICE
AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
Through this work, AEMO and Powerlink have identified the need, depending on power system conditions, to constrain the output of three generators in North Queensland to maintain power system security.
The constraint equation is expected to limit generation from the three generators depending on power system conditions. The generators are Mt Emerald Wind Farm, Haughton Solar Farm and Sun Metals Solar Farm.
The constraint equations are: Q_NIL_STRGTH_MEWF, Q_NIL_STRGTH_HAUSF, Q_NIL_STRGTH_SMSF. These will be implemented at 1500hrs EST today.
The minimum generator combinations and limits are:
1 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 4 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 4 x Kareeya, 2 x Barron Gorge: 100% output
2 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 4 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 4 x Kareeya, 1 x Barron Gorge: 80% output
3 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 4 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 2 x Kareeya, 1 x Townsville GT: 80% output
4 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 4 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 2 x Kareeya, 1 x Barron Gorge: 70% output
5 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 4 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 4 x Kareeya: 70% output
If these combinations are not met all three generators have a limit of 0 MW and 0 inverters.
