Repeat Problem 6.32 with the slack bus voltage changed to \(1.0 \angle 30^{\circ}\) per unit.

Problem 6.32

For a two-bus power system, a \(0.7+j 0.4 \) per unit load at bus 2 is supplied by a generator at bus 1 through a transmission line with series impedance of \(0.05+j 0.1 \) per unit. With bus 1 as the slack bus with a fixed per-unit voltage of \(1.0 \angle 0\), use the Gauss-Seidel method to calculate the voltage at bus 2 after three iterations.
