The bus admittance matrix for the power system shown in Figure 6.24 is given by

With the complex powers on load buses 2, 3, and 4 as shown in Figure 6.24, determine the value for \(\mathrm{V}_{2}\) that is produced by the first and second iterations of the Gauss-Seidel procedure. Choose the initial guess \(V_{2}(0)=\) \(V_{3}(0)=V_{4}(0)=1.0 / 0^{\circ}\) per unit.
