If u don't know answer skip it don't copy from chegg otherwise ready for 10 dislik
Figure 1 shows the one-line diagram of four-bus power system with generation at bus 1 and bus
4. The voltage at bus 1 is V1 =1.05 <0° per unit. The Voltage magnitude at bus 4 is fixed at 1.11 pu
with a real power generation of 250 MW. The scheduled loads on buses 2 and 3 are marked on the
diagram. Line impedances are marked in per unit on a 120-MVA base. Create the admittance matrix
bus using KCL method.
