A generator bus(with 1.0 per unit voltage)supplies a 180MW, 60Mvar load through a lossless transmission line with per unit (100 MVA base) impedance of j0.1 and no line charging. Starting with an initial voltage guess of 0.8<0◦,iterate until converged using the Newton-Raphson power flow method. For a convergence criteria, use a maximum power flow mismatch of 0.1 MVA.
