Hi all,
I am trying to implement the AC-OPF problem in GAMS (with knitro and ipopt solvers).
There are two versions I created. The first one follows this example https://www.gams.com/latest/psoptlib_ml/libhtml/psoptlib_MultiperiodACOPF24bus.html and it works correcttly and give a correct solution.
In the second version, I tried to follow the model in this paper https://www.tandfonline.com/doi/epdf/10.1080/0740817X.2016.1189626?needAccess=true
Here I used Eq (5)- Eq (11) and Eq (57) - Eq (58) for the power flow equations. This version keeps getting infeasible solution (it should have yielded the same solution as in version 1)
I have attached my GAMS codes for your references. Your help would be greatly appreciated.
Thanks,
Andy
