I'll add my 2 cents. I don't know PSAT, but I can attest to the difficulty
in reproducing exactly the same powerflow solution in two different
software tools, in general. First you have to find out how many features
are implemented and enabled/disabled in each tool; but more importantly,
you have

Thank you so much, that helped a lot.

Dear Fellow Member,
I ran load flow analysis on a IEEE-14 bus system using MATPOWER, PSAT and
PowerWorld. Voltage magnitudes as well as phases have slightly different
values in all three tools. However, the difference is not much but I want
to know what causes difference among results obtained
If the system parameters are the same, it could be because the tolerance
levels that were set for the different software were different i.e. the
default power balance mismatch tolerances are not always the same in all
software. Also probably if the VAR limits are active for PV buses,
different
