Hallo Panagis, and thanks for your answer. so just making the mpc.gen(:,6)=0 will disregard the constraint without having to change the impedance. This is great. and if for example I do not want the transformers to be a bottleneck, can I just make their 6th column 0 while keeping the same correct value for the line branches? Thanks a lot.
