I suppose you are using a version of Matlab between 7.6 and 7.9, correct? The test failures are because fmincon's interior-point method (which is now the default, i.e. MATPOWER option FMC_ALG is now 4 instead of 1) was not accurate enough in Matlab versions 7.6-7.9. So if you plan to use fmincon for running optimal power flows (OPF_ALG = 520), I suggest you limit yourself to using the active-set method (FMC_ALG = 1), or update your version of Matlab.
This does not affect the default MIPS solver used when using runopf without explicitly setting OPF_ALG. The tests have been fixed so this won't happen in the next version. -- Ray Zimmerman Senior Research Associate B30 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Jun 8, 2013, at 1:31 PM, Panagiotis Anagnostopoulos <[email protected]> wrote: > Hello, > > I have installed the MATPOWER for OPF problems I face.
