A 4-bus power network is given below along with the information about the buses. The reactances given are on a base of 100MVA. Bus No. 1 2 3 Bus Type Slack PQ PV PQ Bus Data Voltage: 1.020" P-100 MW, Q-70 MVAR P-200 MW, V=1.02 P-250 MW, Q=150MVAR Line Data Line 1-2 (2-j0.03) Line 1-4 (2-0.01+j0.05) Line 2-3 (Z-10.06) Line 3-4 (Z-j0.03 a) Using the Gauss-Seidel method, calculate the bus voltages for two iterations. b) Considering that the solution converged after 2 iterations, calculate the line flows, line losses and slack generation
