It works, perfectly!!! Thank you a lot!!! Now I can start with the transient analysis!!! Fortunato

Two things.1. You have specified 2 reference buses. I think bus 2 should be type 1 (PQ bus). 2. The load at bus 2 is way too large. Try backing it off to about 250 (or 235 if you use the Qd = 28 MVAr as shown in the figure) and you'll see that the load flow converges, but the voltage at that bus is on the order of 0.7 p.u. If you increase the load much beyond that the voltage collapses and the Newton power flow does not converge.The transformer ratio can be entered in column 9 of the branch matrix. The transformer model used is described in section 3.2 in the manual (http://www.pserc.cornell.edu/matpower/manual.pdf).
