Dear all, I have a convergence problem when running the OPF. When I used the Matpower vesion 4.1 my casefile converged in pf but not in opf. I have recently installed the new version of Matpower 5.1 and when running the opf I get the following message which I do not understand: ??? Error using ==> classCannot change the number of fields of class 'opf_model' without first typing 'clearclasses'.Error in ==> opf_model.opf_model at 66 om = class(s, 'opf_model', om);Error in ==> opf_setup at 202om = opf_model(mpc);Error in ==> opf at 200om = opf_setup(mpc, mpopt);Error in ==> uopf at 117 [results, success] = opf(mpc, mpopt);Error in ==> runuopf at 78[r, success] = uopf(casedata, mpopt); Could someone explain to me what the problem is? Thank you for any suggestion. You can find attached the case file (mpz) the results of the pf (resultsLF) and the results of the opf (resultsOPF) when using Matpower 4.1
Any suggestion on how not to get that error message and/or how to reach convergence is welcome, Thank you, Gamze
