If baseMVA is 100, then Bs in pu should be 0.19 .

Dear
Dr Zimmerman and all friends
I
have written one load flow code with Gauss-Sidel and one with Newton-Raphson.
Both of them lead to the same results. For validating my codes I compared the
results with matpower results. I compared the results in IEEE 14, 30 and 57 test
systems. In all cases the angles of
voltages and real power of lines are roughly the same with Matpower, but the
voltage
amplitudes and reactive power of lines are different. I thought much to find
the problem. Mostly I skeptical about inputting Bs (shunt suceptances in
busses). In Matpower Bs
is defined as : “ shunt suceptance (MVAR
injected at V=1 pu). For inputting Bs in
my code I have done followings: (19 is the data for Bs in 14 bus test system).
the simple formulation for computing Bs in Pu is attached.
So,
in my load flow code I have put Bs=0.0524 pu, is it correct? You think which
part of my load flow code can be wrong and why my results are not the same with
Matpower?
Your
cooperation is highly appreciated

Ahmad
