Hello Everybody,

I have a problem with Matpower. When I try to run a normal power flow (pf) on a simple case from the preinstalled cases from the Matpower like case 30 for example it runs properly. But when i try to run the optimal power flow (opf) for the same case it gives me the following errors.

MATPOWER Version 5.0, 17-Dec-2014 -- AC Optimal Power Flow Error using have_fcn>vstr2num Too many input arguments.

Error in have_fcn (line 185) if vstr2num(v.Version) >= 6.005

Error in opf_execute (line 80) if have_fcn('pdipmopf')

Error in opf (line 225) [results, success, raw] = opf_execute(om, mpopt);

Error in runopf (line 96) [r, success] = opf(casedata, mpopt);

I did not change any input data or any variable from the case.. And I installed the Matpower file as it should be, I unzipped it in the Matlab document files.

The strange thing is that it runs pf but not opf.

So any suggestions..?

Thanks in advance
