Thank you for your answers! Yesterday i tested the consequences of changing the bus / gen / branch order and all seems to be ok.
In particular, case300.m is very similar to my case, because for example bus numbers "jump" to 664 to 1190 and from 2040 to 7001, so i've tested also that if any number misses MATPOWER still works. I've also tested the influence of switching F_BUS and T_BUS: it still works, but PAY ATTENTION: obviously if in the branch there is a transformer, you CAN'T change F_BUS with T_BUS! The important thing, as Dr. Zimmerman said, is that every bus has its unique ID. Thank you all.
