= 6.11. In the two-bus system shown in Figure 6.24, bus 1 is a slack bus with V₁ 1.040° pu. A load of 100 MW and 50 Mvar is taken from bus 2. The line impedance is 212 = 0.12+ j0.16 pu on a base of 100 MVA. Using Newton- Raphson method, obtain the voltage magnitude and phase angle of bus 2. Start with an initial estimate of V21(0) = 1.0 pu and 62 (0) two iterations. = 0°. Perform 1 о V₁ = 1.020° FIGURE 6.24 212=0.12+ j0.16 One-line diagram for Problem 6.11. I 2 100 MW --- 50 Mvar
