An astute reader noted to me about the Central-to-Southern constraint binding today in Queensland, one of the rare days where I did not have an ez2view dashboard display alerting me to its occurrence.
However I do have a brief period now to wind back the clock through “Time Travel” in the software to snapshot the 12:25 dispatch interval as an example of what happened:
The particular constraint bound (Q_CS_1750) is of the form Left Hand Side (LHS) ≤ Right Hand Side (RHS), with the Left Hand Side containing all the terms that NEMDE (the dispatch engine) tries to optimize – which in this case means reduce or “constrain down” the output:
One of three founders of Global-Roam back in 2000, Paul has been CEO of the company since that time.
As an author on WattClarity, Paul's focus has been to help make the electricity market more understandable.
Spurred on by our competition (but with an interest that’s much broader) we have a look at how Queensland demand has trended – and find a couple of quite remarkable things occurring…
In this article we look more closely at 1st and 2nd February 2022 – and particularly at where and when the changes in rooftop PV occurred, narrowing our assessment to south-east Queensland regions. It follows on from Part A which inspected how Queensland rooftop PV output varied at the state level.
Looks like being an interesting day on Wednesday next week (14th February 2018) with high temperatures currently forecast for parts of both QLD and NSW
