(b) Figure Q2 shows a power system network. The generators at Bus 1 and Bus 2 are represented by their equivalent current sources with the reactance in per unit on a 100MVA base. The lines are represented by n model where the series and shunt reactances are expressed in per unit on a 100MVA base as well. However, the load located at Bus 3 and Bus 4 are expressed in MW and MVar. (i) Reconstruct the network impedance shown in the figure into the network admittance by assuming the voltage magnitude at Bus 3 and Bus 4 are 1.0 per unit, respectively. (11) Calculate the bus admittance matrix of the system.
