For a two-bus power system (Figure 4), a 0.6+j0.5 per unit load at bus 2 is supplied by a generator at bus 1 through a transmission line with a series impedance of 0.08+j0.16 per unit. With bus 1 as the slack bus, use the Gauss-Seidel method to calculate the voltage at bus 2 after two iterations (Start with a per-unit voltage of V(0)= 1.0 20, V(0)= 1.0 20 per unit).
