context for _GOC cases? #44

Closed frederikgeth closed 4 days ago

frederikgeth commented 6 days ago

I'm looking for more information on the _goc cases, but the link in reference 45 in the arxiv report appears broken.

I'm curious if there is more background on the _goc cases surviving elsewhere? They seem to have some unique features when it comes to the structure of the mesh of the network. I would love to understand if this has anything to do with real world networks, or if it may be an artefact of a topology which was generated through a statistical model.

Thanks!

This link is currently working, https://gocompetition.energy.gov/

Look at the header of a network file for more information about how it was generated. Many different teams and methods contributed to the goc cases.

Great thanks!

For anyone who ends up here in the future, the tips led me to https://gocompetition.energy.gov/challenges/22/datasets and https://egriddata.org/dataset/sdet-tool. The SDET tool documentation seems to suggest that it wouldn't modify the topology of lines/transformers, just anonymize.

I have a vague recollection of some odd topological features int he SDET data, but I don't recall the details.

It seems resolved, shall we close this issue?

frederikgeth commented 4 days ago

Yeah, fine by me to close it. If anyone has more background on the origin of the cases, I'm curious to learn more.
