Powermodels.jl SDP relaxation

Dears

I have a question regrading the Powermodels.jl package. Does it support the SDP relaxation? I have seen that it was mentioned in the documentation that it is supported (SDPWRMPowerModel). However, it didn’t work even though I have used SDP solvers like SeDuMi and SCS. I would appreciate your update in this regard.

Regards

Yes. Use SDPWRMPowerModel.

it didn’t work

What was the error?

Thanks for the reply. The error that I have received is

LoadError: MethodError: no method matching setsolver(::JuMP.Model, ::SeDuMi.Optimizer)

Closest candidates are:

Any update?

The log you show indicates an issue with the solver interface. I recommend trying SCS or Mosek, these are the ones I have used to developing and testing the SDP formulations.

What version of PowerModels are you using (import Pkg; Pkg.status()). setsolver looks like it is for an old version of JuMP.

7

PowerModels v0.9.8

SCS worked, but Sedumi didn’t

8

The latest release of PowerModels is 0.18.0. Your version is two years old.

I would suggest that you don’t use JuliaPro, and just install the latest point release of Julia instead: Download Julia

How to call Mosek for solving the SDP problem in PowerModels?

I answered your other question: Using Gurobi with PowerModels - #2 by odow

using MosekTools and Mosek.Optimizer.
