AEMO’s defence of “we didn’t know” underscores case for change | Renew Economy

The Australian Energy Market Operator insists it was completely unaware about the nature of the fault ride-through settings on wind farms in Australia, even though the issue had been addressed and resolved in Europe a decade ago.

In the third, and most detailed, report into South Australia’s state-wide blackout in September, AEMO says it did not know that wind farms built in Australia had limits on their “fault-ride through” settings, which govern whether a wind farm can continue operating with multiple network faults of the type that occurred when tornadoes tore down three major transmission lines.
