I have been using PSAT to model a 24 bus bar power system, which is in PSAT Library. Yet, I have an error during power flow test. This error pops up, when I click on Power Flow button:
Error using fprintf Invalid file identifier. Use fopen to generate a valid file identifier.
Error in fm_wcall (line 49) count = fprintf(fid,'function fm_call(flag)\n\n');
Error in fm_spf (line 41) fm_wcall;
Error in fm_set (line 720) fm_spf
Error while evaluating uicontrol Callback
Although I do know that PSAT is not a TOOLBOX supported by matlab, even your short reply could be certainly helpful.

Hello Gentlemen, Dr., and Prof.:
Help me here.
I installed PSAT in MATLAB but when running power flow it shows:
Error using fprintf Invalid file identifier. Use fopen to generate a valid file identifier.
Error in fm_wcall (line 49) count = fprintf(fid,'function fm_call(flag)\n\n');
Error in fm_spf (line 41) fm_wcall;
Error in fm_set (line 720) fm_spf
Error while evaluating uicontrol Callback
Please help me.

Hello Muataz Fahad... Did you solve your problem?

This problem can occur if you start running psat from the psat directory and you do not have write access to the psat directory.
psat keeps a record of which directory you were in when you start running it, and in some cases tries to write file fm_call.m into that directory.
The work-around is to make sure that psat is on you MATLAB path, and to start it running by name when you are cd'd to a directory that you have write access to.

It appears to be a link to code for some paper.

Hello everyone;
I m trying to run the load flow usng the PSAT, I have 5 generators and it is a 1 slack and 4 PV bus system. But when we run the power flow we are not getting the load flow, we are getting the error as, ''the convergence is increasing'' and ''convergence likely not reachable.'' What could be th possible problems? would be glad if anyone of you coould answer.
