Hi, I am running a load flow on a very large grid but I cannot make it converge using Matpower. I have looked at all the discussions on the subject and test various things but neither the pf nor the opf function converge.
When I look at the results (of the non-convergent solution) I see that Matpower could not compute the following values which are assigned to NaN: - Voltage magnitude and angle of buses - Reactive power output of generators - Reactive and active power injections at node from and to of each line When I tried to check the scaling factor (using the solution proposed on the website:5. Why does MATPOWER power flow not converge?<http://www.pserc.cornell.edu/matpower/#pfconvergence> v.) I got the following error: ??? NaN's cannot be converted to logicals. Error in ==> printpf at 177 nzld = find((bus(:, PD) | bus(:, QD)) & bus(:, BUS_TYPE) ~= NONE); Error in ==> runcpf at 392 printpf(results, 1, mpopt); Given this, if anybody has an idea of what I should try, check, change to make the computation converge? Thank you, Gamze
