Santiago,
I'm guessing you have the optional TSPOPF package installed, right? For some
reason the default solver (PDIPM) is encountering a singular matrix. I don't no
yet why, but some other solvers (MIPS, Ipopt, Knitro, MINOPF) seem to work fine
on that problem.
mpc=loadcase('t_case9_dcline');
mpc=toggle_dcline(mpc, 'on');
opt=mpoption('OPF_ALG', 560);
results=runopf(mpc, opt);
I notice that 520 (fmincon) crashes on this problem. There is probably a bug
somewhere with initializing the algorithms correctly. I'll look into it.
Thanks for bringing this to my attention,
