You are expected to perform hand calculations and solve for all the unknown state variables using Newton-Raphson method. Please limit to two iterations.

6.8. Figure 54 shows the one-line diagram of a simple three-bus power system with generation at buses 1 and 3. The voltage at bus 1 is V1 = 1.02520 per unit. Volt- age magnitude at bus 3 is fixed at 1.03 pu with a real power generation of 300 MW. A load consisting of 400 MW and 200 Mvar is taken from bus 2. Line impedances are marked in per unit on a 100 MVA base. For the purpose of hand calculations, line resistances and line charging susceptances are neglected.
