Dear Samuel, I really appreciate your help, thank you. After reading your reply I have made some further tests, and I believe that the very issue is the branch matrix too. The ACOPF actually converges with your corrections on the branch matrix, and I have noticed that it still works even keeping t

Hi Enrico, I had a quick look at your case. Firstly, the results you get when running an DC PF on your case are normal. The active power is fixed at all Load and Generator buses, and therefore only the slack bus can add/remove active power to the system in order to find a solution. Given that a
