Thank you very much, but the problem has been solved.
help caseformat:
Generator Data Format
1 bus number
(-) (machine identifier, 0-9, A-Z)
2 Pg, real power output (MW)
3 Qg, reactive power output (MVAr)
4 Qmax, maximum reactive power output (MVAr)
5 Qmin, minimum reactive power output (MVAr)
6 Vg, voltage magnitude setpoint (p.u.)
Vg in the generator data is express by p.u..
The result of power flow does not change, though column basekV of case9.m. is
changed to 220kV from 345kV.

hello,
the possible answer is:
you should change column Vg in the generator data of case9.m.
regards
