AEMO has adjusted the formula (i.e. constraint equations) used to manage system strength in South Australia, which has been (since mid-2017) by constraining down the output of wind farms under certain conditions.
An article that sums up some decidedly un-quick calculations we’ve performed – looking over an 8 week period to 13th September to estimate how much wind power has been curtailed by the AEMO.
A quick note about high wind speeds in South Australia this afternoon leading to AEMO constraining wind farm output down for System Strength reasons.
