Is your feature request related to a problem? Please describe. Current gas flow formulation uses BigM constants that lead to bad solutions if they are selected correctly.

Describe the solution you'd like Review the current formulation and check alternative formulations to either use one without BigMs or determine the value BigM should get more efficiently.

Describe alternatives you've considered One starting point is this paper: https://optimization-online.org/wp-content/uploads/2014/10/4580.pdf

Additional context double-check more recent works on this topic.

@g-moralesespana, We might want to use some of the findings we got from Thomas' research. Any thoughts?
