Article: Further analysis of the (very rare) double-islanding events of Saturday 25th August 2018

The multi-region islanding event on Saturday 25th August was a very rare event – perhaps the only one’s that occurred in the history of the NEM. It has generated plenty of questions – and driven our analysis further. We share some more observations here, and keenly await the draft AEMO report.

Article: When the NEM’s Largest Generating Unit Trips …

A follow-on to my earlier article of a couple weeks ago, looking at another instance where a team effort was required to counter a drop in system frequency following the loss of generation at a large power station (this time the single unit Kogan Creek power station – the largest single unit in the NEM).

Article: FCAS in Action – What Happens When a Generator Trips? (or Never let the data get in the way of a good story)

Understanding the FCAS response by all generators when a unit trips in the NEM. A detailed look at the Loy Yang A unit trip in December 2017 and the contribution of the Hornsdale Power Reserve.

Article: Power System Frequency – What is it doing? – Why does it matter?

The East Coast power system of Australia has the worst frequency regulation in the developed world. This puts the system at risk whenever an event occurs which requires the generators to respond quickly – they can’t respond quickly if they have to wait for the system frequency to go outside its control system dead band.

Article: Short term forecasting of wind power plant generation for the provision of ancillary services

As NEM wind power plants progressively work towards implementing FCAS, the criticality of ensuring that the power system either a) takes account of the variability in the wind forecasts coming from the wind power plants in the coming 5-7 minutes and follows the wind direction, or b) sets an appropriate dispatch level to ensure wind variability is minimized, becomes even more important for market and power system operators.
