Optimal restoration path problem - Infeasible solution

Post by ManT »

Hi,

I have modelled the optimal restoration path problem in a 5bus network using AC-power flow formulation. This is modelled as a MINLP problem and solved with BONMIN solver.

My formulation yields an infeasible solution. Can anyone please help?

The gams code is attached.

Thank you.

Hi
You might have too many equality constraints as it has too few degrees of freedom. Or/and you have fixed or bounded too many variables.
You might remove some of the constraints and/or bounds to see where the problem is.
Cheers
