Dear Professor Zimmerman Thank you so much for you help and guidance. It helps me so much and it works fine.

If you solve the OPF (which allows the generator voltages to vary between VMIN and VMAX) and then use the voltages from that solution as the setpoints in gen(:, VG), then the power flow solves fine. -- Ray Zimmerman Senior Research Associate 211 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Jul 7, 2011, at 3:34 PM, Esmaeil Ghahremani wrote: Hello All Dear Matpower Users, > > >The RTS-96 Test System data could be found from this link: >http://www.ee.washington.edu/research/pstca/rts/pg_tcarts.htm > > >From google searching, I have found the following link for the Matpower format >of RTS-96 Test system: >http://www.parallelcoding.com/wp-content/uploads/Research/MCSPruning/case96.m > > >I rearranged the above file in the form of attached file (They are exactly the >same).
