We've started exploring the constraint data from the QLD region for back on Tuesday 25th May 2021 (with the Callide C4 catastrophe) and here's some initial information.
Part 5 in an expanding series, looking at what happened in QLD on Tuesday 25th May 2021 - this one looking at system frequency.
Looking back at Tuesday 13th April 2021 - a day in which the ex-tropical cyclone Seroja in Western Australia caused some wobbles in rooftop solar PV output in South Australia.
A different type of market notice today (speaking of potential curtailment of embedded generation in South Australia) points to the future ... accelerated by Heywood repairs in this instance.
Guest author Allan O'Neil puts together an in-depth explainer about system strength and looks at the current approach to system strength management in South Australia, its impacts and the imminent installation of synchronous condensers...
In this (lengthy) article today, Paul McArdle uses the newly released GSD2020 to take a look at the units that were most frequently impacted by constraints during calendar 2020 - with a view to...
In part 4 of this expanding Case Study of the unexpected price spike on Tuesday 13th Oct, linked to a large & sudden drop in output across 10 solar farms, we take a quick...
In part 3 of this expanding Case Study of the unexpected price spike on Tuesday 13th Oct, linked to a large & sudden drop in output across 10 solar farms, we dig deeper to...
Based on some preliminary analysis of the Powerlink's 'Qdata' set (available in ez2view) we present our current hypothesis as to the sequence of the events yesterday in the QLD region, where 600MW of solar...
Guest author, Allan O'Neil, invests some time to explore a number of different aspects of Easter Saturday (11th April 2020), each noteworthy in their own right (including low demand, high percentage share renewables, negative...
A detailed look at two specific trading periods in the day (Tuesday 24th July 2018) that saw negative dispatch prices occur at the start of trading periods - hence provided a case study for...
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.
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.
A quick note about high wind speeds in South Australia this afternoon leading to AEMO constraining wind farm output down for System Strength reasons.
