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.

Article: Let’s Keep Talking About FCAS

Following on from the Let’s Talk About FCAS post, the focus of this post is the business case and subsequent optimisation challenge for getting involved in FCAS, now that the technical performance components have been mostly addressed.

Article: Victorian demand rises above 9,000MW – which (in combination with other factors) leads to a volatile day in the southern regions

On a day when high temperatures drove demand in Victoria above 9,000MW (and NEM-wide demand above 30,000MW) we saw some price volatility – with prices in VIC and SA up around $14,000/MWh

Article: Friday 12th January saw high instantaneous wind output in South Australia (but not quite a new record)

Prompted by a tweet referencing our RenewEconomy-sponsored NEMwatch Widget, we have a quick look at all-time peak instantaneous aggregate wind output in South Australia

Article: AEMO updates generator combinations for SA system strength

AEMO has adjusted the formula (i.e. constraint equations) used to manage system strength in South Australia, which has been (since mid-2017) by constraining down the output of wind farms under certain conditions.

Article: Why is wind production being curtailed (or “dispatched down”, more strictly speaking)?

It was inevitable that Semi-Scheduled plant would start to experience times when they are dispatched down. It’s a big prompt to take next steps up the learning curve.

Article: How much wind-powered electricity production has been curtailed in SA since these new constraints were invoked?

An article that sums up some decidedly un-quick calculations we’ve performed – looking over an 8 week period to 13th September to estimate how much wind power has been curtailed by the AEMO.

Article: On Saturday 2nd September, AEMO reacted to Severe Weather Warning by imposing limits on interconnector

On Saturday 2nd September, AEMO responded to a BOM-issued “Severe Weather Event” warning by reducing flow capacity west on the Heywood link. Here’s how that looked…

Article: Wind production in South Australia roared out of the June doldrums to a new production record in July 2017

From one extreme (perhaps lowest ever in June 2017, on like-for-like) to the other (new record production) in the space of just one month for aggregate wind in South Australia

Article: Wind Farm output in SA constrained, again, by AEMO’s “System Strength” constraint

A quick note about high wind speeds in South Australia this afternoon leading to AEMO constraining wind farm output down for System Strength reasons.
