Hai Ning Xie,
Its working fine for me. Here I am giving the test results for three
different cases.
--------------------------------------------------------------
>> mpc=loadcase('case9');
>> mpopt=mpoption('PF_DC',1);
>> [r, success] = opf(mpc, mpopt);
MATPOWER Version 4.0b2, 19-Mar-2010 -- DC Optimal Power Flow
Matlab Interior Point Solver -- MIPS, Version 1.0b2, 19-Mar-2010
Converged!
>> mpc=loadcase('case30');
>> [r, success] = opf(mpc, mpopt);
MATPOWER Version 4.0b4, 21-May-2010 -- DC Optimal Power Flow
MATLAB Interior Point Solver -- MIPS, Version 1.0b4, 21-May-2010
Converged!
>> mpc=loadcase('case300');
>> [r, success] = opf(mpc, mpopt);
MATPOWER Version 4.0b4, 21-May-2010 -- DC Optimal Power Flow
MATLAB Interior Point Solver -- MIPS, Version 1.0b4, 21-May-2010
Converged!
----------------------Possible ways to fix this error ---------------
1. Can you check you data file, which has any modified elements?
2. Check the Matlab root directory from where you are running the program.
(bcz it may take files from local directory if available.)
3. You can upload your matlab data file to this forum, so that other can
check and update you.
