First of all thank you for the help and the references, it has been very usefull.
I understand that I can alter the Opf using for example the callback functions. Let's say for example I need to add a generator at a predetermined busbar (12) and maximize it's output (costs are no constraint, the only constraints should be whether the system can handle it= equipment limitations) So first I simply add a generator at bus 12. The callback I need to use to alter constraints and variables is the one on formulation. The constraints of the 14 bus netwerk shoudn't change (same limits of equipment etc) But my objective function that should be maximized is simply f(x)=S (with S the output in MVA of the added generator) How do I then change the objective function from minimizing the costs to maximizing the added generator output?
