[pypsa] Using HiGHS solver in pypsa

[Toni Vayá Soler]

Dear colleagues,

It has been a while without using pypsa.

It is my understanding that now pypsa supports HIGHS solver. I am in a Windows environment and I have installed HiGHS using pip install highspy.

Then, to call HiGHS, is it as simple as n.optimize(solver_name="highs") or something similar?

Thank you in advance for your feedback,
Antonio

Hi Toni,

I recently switched from GLPK to HIGHS (as installing GLPK became a real pain in the neck for me at least). 

Your understanding is correct, just code:

network.optimize(solver_name = 'highs') and it will work (assuming it installed correctly via Pip)

Best,

Fernando

Hi Fernando,

It seems that Gurobi has the highest performance.
