Cautioning readers that I am a novice at reading frequency data in this manner, I take a first look at how the frequency in Melbourne and South Australia varied at the time of the...
Guest author (and power system control specialist), Kate Summers, looks at what's changed since she published a paper on frequency control in the NEM back in January 2017.
