Hi All, I have wrote backward-forward load flow code, Now I am testing it, if it works good, I will send you all to use it. Also I propose to use it in future version of MATPOWER. Thank All.

I have not really kept up with the literature in distribution power flow since then, but I am not aware of any earth-shattering discoveries in the area since 1995. Regarding your response to the list ... I expect you'll see it come through eventually. Sometimes things get delivered out of order for some reason. -- Ray Zimmerman Senior Research Associate 428-B Phillips Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Jul 17, 2007, at 8:50 AM, Jovan Ilic wrote: Would you consider your PhD still up to date or can you give us a reference to some Earth shattering discoveries since 1995? By the way, my e-mail never made it to the list but your response did? Is that how the list is set up or am I e-mailing to a wrong address? Ray Zimmerman wrote: Just don't ask for the code ;-) My PhD thesis is available at http://stealth.pserc.cornell.edu/ray/pubs/PhDThesis.pdf and does cover a number of algorithms including the backward/forward variations mentioned. Unfortunately, the code was tightly coupled with a proprietary data format and has never been refactored to be independent of that.

He discussed, I think, three different algorithms with detailed formulas, etc. He gives all the formulas, data structures, etc. You could write your own in no time and no package can be more usable than your own. I know it was done in 1995 but I do not expect any breakthroughs since then.

I am working on planning of Distribution networks using GA for my MSc Thesis. In performing Load flow I encountered a problem when using matpower. In Radial networks the newoton raphson method converges and I couldn't obtain Voltages, I have asked some people, they say I must use forward backward loadflow, Does someone has it's code in MATLAB M-File?????? I am really in need. please send me it if you have it, Thanks beforehand thank you all goodbye
