and for a clarification UC is surely in the scope of PowerModels and there is already basic support for it in the modeling layer.

@ccoffrin
@mtanneau, usually UC does not include a network model, so I would not say UC = OPF + ... but in general there is not a lot of consistency in the industry what they mean by different version of the UC problem. Economic Dispatch and OPF are some what interchangeable in my experience (the early papers on AC-OPF called it Economic Dispatch); but I would not worry too much about the names of things in power systems, there is just not enough consistency to draw a clear line in most cases

@mtanneau Thanks for posting about UnitCommitment.jl here. I'd be very glad to answer any questions about the package. This is something we had been using internally at Argonne and we decided to release it as open source. Contributions are very welcome. We are also exploring how to make it interoperable with other related Julia/JuMP packages (specifically, PowerModels.jl and PowerSimulations.jl)
Carleton Coffrin
@ccoffrin
@iSoron, congrats on the release! I head it was in the works and its nice to see it. Happy to discuss paths for interoperability with PowerModels!

We have added a page about modeling with PowerSystems.jl and JuMP here

@/all The monthly developer calls for November and December were each moved earlier one week to Nov. 19 and Dec. 17, respectively. The time is still 2pm US Eastern. This was to avoid conflicts with the US Thanksgiving holiday and Christmas.

@joehuchette
Is there a high-res png of the JuMP logo floating around anywhere?
Oscar Dowson
@odow
Might be on the NumFOCUS drive. I'll have a look
Do you have access? JuMP>Logos. Otherwise I can email you it
Joey Huchette
@joehuchette
Awesome, thanks Oscar

@mlubin
@/all Reminder: November's monthly developer call is today at 2PM US Eastern time. Ping me or @odow for an invite. The agenda is relatively open, please add any items you'd like to discuss.

@mtanneau
I added an item w.r.t MatrixOptInterface, but feel free to dismiss if not relevant.

New release is tagged. Things should work after an update.

Why is it that a new MUMPS binary can be tagged without some CI checking that Ipopt still works?
Oscar Dowson
@odow
New documentation, including examples in the docs: https://jump.dev/JuMP.jl/dev/!
@mlubin, this was really a problem in the Ipopt_jll build script, it didn't have strict compat bounds. The next issue was that CI passed in Ipopt.jl, because the version resolver picked the correct versions, but if you ran ] add Ipopt, a different set of packages got picked.

Recently I started seeing the follow message,
[ Info: Precompiling Ipopt [b6b21f68-93f8-5de0-b562-5493be1d77c9]
┌ Warning: Module MathOptInterface with build ID 472455042652337 is missing from the cache.
│ This may mean MathOptInterface [b8f27783-ece8-5eb3-8dc8-9495eed66fee] does not support precompilation but is imported by a module that does.

[ Info: Skipping precompilation since __precompile__(false). Importing Ipopt [b6b21f68-93f8-5de0-b562-5493be1d77c9].
Any ideas on what might be up?
Oscar Dowson
@odow
Is this in a instance with multiple proc?
*procs?
Carleton Coffrin
@ccoffrin
Ya, but usually, as long as the code was precompiled on a single thread first the cache works out, but that does not seem to resolve this one for some reason
Oscar Dowson
@odow

as long as the code was precompiled on a single thread first the cache works out

This was my only suggestion. Not sure

Carleton Coffrin
@ccoffrin
K, my usual tricks to recompile the cache do not seem to work. I'll try to figure out a MWE.

Is there a list of all JuMP solvers?
freemin7
@freemin7
Do we have a bridge for quantization of non-linear terms? (Possibly doing Taylor expansion sin/cos/other stuff )?
Oscar Dowson
@odow
No. Nonlinear is a second-class citizen at this point.
freemin7
@freemin7
Why is that the case?
Is it just a lack of somebody caring about it?
Miles Lubin
@mlubin
See the discussion at jump-dev/MathOptInterface.jl#846

@freemin7
Yay, i found another German NLP solver, this one is open source and comes with an interface for reformulating dynamic optimization problem as NLP probelms. I am not finished making the previous one JuMP compatible.

Is anyone else seeing build failures on GH actions? https://github.com/jump-dev/JuMP.jl/runs/1471402527

@odow
Seems like it is related to a recent release of ForwardDiff: jump-dev/JuMP.jl#2390

could someone add a DOCUMENTER_KEY secret to Convex.jl? re- jump-dev/Convex.jl#406
Oscar Dowson

Doing it now
