Dear Dr Zimmerman; Thanks for sending me your thesis, which was very useful. Could you please provide me with a reliable MATLAB code for running backward-forward sweep load flow on a radial distribution matpower case? Zeinab Ghofrani

Feel free to look at my dissertation and the references in it for some ideas. -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Oct 5, 2012, at 2:37 AM, Zeinab Ghofrani <[email protected]> wrote: Dear all; > >I'm tryning to run power flow on the 32 bus distribution system described in >the following paper: >M.
