Incompitable packages
Closed this issue · 2 comments
Dear Sir,
Recently I installed the GasPowerModels package in Julia. Then I tried to add the Pavito solver. It was unsuccessful. It seems that the JuMP versions compatible with Pavito are different from those with GasModels. Without the Pavito solver, GasPowerModels cannot run. Could you please give me some advice on this issue?
The GasPowerModels is really a powerful tool to model the gas and power coupling scenarios. Many thanks for your sharing.
Sincerely yours,
Sean

Hi Sean, the core issue here is that Pavito has not been updated to JuMP v0.19+, while most other solvers and related tools have been updated (including this one). You can follow this issue for when Pavito will be available in JuMP v0.19. jump-dev/Pavito.jl#7
In the meantime the open source solver Juniper.jl should work. We can also recomend Gurobi as a high performance solver for some classes of problems uses in GasPowerModels.
Many thanks.
