Hi all

I am going to pass on the original question and instead change the subject to policy‑oriented modeling that I sometimes raise.  Four modeling frameworks recently ran a very simplified cross‑model comparison in the US (PDF attached as per scientific research):

• Henry, Candise L, Hadi Eshraghi, Oleg Lugovoy, Michael B Waite, Joseph F DeCarolis, David J Farnham, Tyler H Ruggles, Rebecca AM Peer, Yuezi Wu, Anderson de Queiroz, Vladimir Potashnikov, Vijay Modi, and Ken Caldeira (15 December 2021). "Promoting reproducibility and increased collaboration in electric sector capacity expansion models with community benchmarking and intercomparison efforts". Applied Energy. 304: 117745. ISSN 0306-2619. doi:10.1016/j.apenergy.2021.117745.  Closed access.
  

Simple means one single node and no power flow in sight!  But this does represent a start in a public policy context.

Also to note that Renewables Grid Initiative (RGI) and Hitachi Energy (HE) have begun a collaboration on exactly that style of modeling.  The first such model outside of academia, government consortia, or NGOs that I know of.

Also of interest perhaps is a recent US supreme court decision in the context of the United States that refused to adjudicate on whether APIs attracted copyright but opined that if they did, that fair use would apply:

• Supreme Court of the United States (5 April 2021). Google LLC v. Oracle America, Inc.. Washington DC, USA: Supreme Court of the United States. Docket no. 18–956. Argued 7 October 2020 and decided 5 April 2021.

• Brandom, Russell (5 April 2021). Supreme Court sides with Google in Oracle's API copyright case. The Verge.

So I guess the question then arises as to the licensing on the APIs under discussion?  MIT perhaps?

Noting too that there would be a case for exposing this set of APIs more widely — and perhaps even to the public if security considerations allow — under statutory reporting considerations.

Finally, could EPRI Ireland email me offlist?  I tried really hard to find contact emails on the web but failed.  I am interested in the reference architecture being developed in the context of the kind of modeling above. TIA!

And sorry to Markus for forking his original posting, Robbie

Hi,

as discussed in the last TAC meeting, one deliverable of the DAWG could be a set of generic (not implementation specific) API specifications for applications like simulation, state-estimation and forecasting.
The idea is to bring different LFE projects together on API level and make it easy for users to switch between implementations. For example, users can adopt the LFE simulation API in their tooling first and then compare different implementations available in LFE to understand better which one is the most suitable one for their application.

We (SOGNO, OpenSTEF) are working on a first example related to forecasting. It will be based on Alliander's OpenSTEF API. Let me know if you are interested in contributing to this effort.
When this is ready, I would like to organize another DAWG meeting to discuss the outcome.

This is just to keep you informed about what is happening even though we do not have regular DAWG meetings currently.

Cheers
Markus
