Dear Matpower users, I have a confusing problem when I am doing some research to improve the optimization of PF problem and OPF problem both.
I solve the PF problem by Newton-Rapfson (NR) method, and OPF problem by Primal-dual Interior Point method (PDIPM). I want to figure out the relationship between the PF and OPF solving process. Do we need a complete PF solving process (using NR) during the OPF solving process (using PDIPM)? In other words, Does the solving process of the OPF problem (using PDIPM) contains many PF calculations? If Yes, in which step the PF is calculated ? and if No, why ? I've been puzzled by this problem for a long time, please help if you clear the answer. Thank you very much. Sincerely, Walter
