Dear Sir,
I used MATPOWER function 'runopf' to solve some opf problems and I found that
the MATLAB always shows the warning as indicated below when the MATPOWER cannot
find a feasible solution (which means some constraints are violated and
accordingly result.success=0).
Warning: Matrix is close to singular or badly scaled.
Results may be inaccurate. RCOND = 4.287473e-029.

In opf at 507
In runopf at 73
Can you advise me some possible solutions to avoid such warning?
Thanks
