Hey @GbotemiB, did you check the result of the the test config with the current main in last couple of days?

@cpschau caught a small bug that caused the model to be infeasible, and is now corrected in the main branch since Friday afternoon.
Interested to know if this solves the objective value of nan in the test config without the need for load shedding

[GbotemiB]

@hazemakhalek, I haven't checked against the latest changes. I will check and confirm the results.

As communicated with @GbotemiB, the nan issue is only solved with the load shedding for now. An issue is now added to revisit this later.

I agree with @davide-f, the PR is ready to merge.

Everything looks good and as agreed
