6.38 A generator bus (with a 1.0 per unit voltage) supplies a 180 MW, 60 Mvar 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 1.0/0°, iterate until converged using the Newton-Raphson power flow method. For convergence criteria, use a maximum power flow mis- match of 0.1 MVA. 6.39 Repeat Problem 6.38 except use an initial voltage guess of 1.0/30°
