Dear Iman, With the load increasing, have you increase the generation from PV buses? I don’t think the network loss could usually increase to nearly 10 times even at static limit. You may double the Pg on PV buses with the load. Then, if you still want to impose the branch thermal limits, you have to code the function to adjust the Pg for PV buses based on participant factors (branch flow sensitivity w.r.t. generation) or others.

I picked 30 bus system with Pg=23.54 MW for the slack bus. Running the power flow with the base loads ,I get 25.97 MW which is quite close to 23.54. Now I want to increase all of the loads 2 times. Running pf I get 236.55 MW for the slack bus . I think in practice thermal line limits doesn’t allow this amount of power dragging from slack bus. I want to make my problem practical by imposing thermal limits on the branches .How can I do that? Thank you in advance for your patience I look forward to hear from you guys Iman
