Figure 1 shows a single line diagram of a three bus power system a) Determine the 3 x 3 per unit bus admittance matrix Ybus. b) For each bus, k=1, 2, 3, identify the variable Vk, Sk, Pk and Qk considered as known and unknown variables c) Using the NR load method for ONE (1) iteration only, determine the voltage and angle at the load bus and calculate the active and reactive power generated at the slack bus for the three bus system shown in figure 1. Start with an initial estimate of |V2|p. u, 0 = 0°and 0 = 0º
