ASSIGNMENT NO.1 For the power system shown in Fig.(1). The transmission lines are identical, and each can be represented by a series impedance of (0.0101 + j 0.0505)pu on 100MVA base. The voltage magnitude at bus2 is kept at 1.03 pu. The bus data are shown on the figure: 1. What functions do the swing bus and PV buses in load flow calculations have? How should they be selected? 2. Write the bus admittance matrix for the given system. 3. Obtain the load flow solution by using Gauss-Seidel method. Perform one iteration 4. Calculate the line losses for the line connecting bus2 to bus 3. 5. Calculate the slack bus power generation. P2= 150 MW PIVI bus 1 IVl=1.03 pu Slack bus Vi=1.0240° pu Sp3= Spi= 30 MW +j10 MVAR 50 MW +j25 MVAR Spz= 20 MW +j5 MVAR Fig. (1)
