AEMO ELECTRICITY MARKET NOTICE

AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.

This advice contains all the combinations for Queensland for system normal cases. Additional information has been included in the limit advice to clarify the requirement to disconnect all inverters/turbines under certain system conditions.
