    The below figure shows a load flow situation. There are 3 generators. Bus 1 is the

    slack bus. The generator on bus 2 is generating at unity power factor, and the another on

    bus 3 is operated under voltage control. The load is all on bus 4.

    We have:1

    U 1 and3

    U 1.05. The power of generator 2 is 70 MW andthe

    power of generator 3 is 60MW. The load powers are P + j Q = 200 + j50 (MVA). Theparameters of transmission lines are showed in below table:
