Power System Frequency Risk Review
The Power System Frequency Risk Review (PSFRR) is an integrated, periodic review of major power system frequency risks associated with non-credible contingency events in the National Electricity Market (NEM).
In accordance with Clause 5.20A.1 of the National Electricity Rules (NER), AEMO is undertaking a PSFRR for the NEM, considering:
- Non-credible contingency events which AEMO expects could involve uncontrolled frequency changes leading to cascading outages or major supply disruption.
- Current arrangements for managing such non-credible contingency events, including the performance of existing emergency frequency control schemes (EFCSs).
- Options for future management of such events.
