11-9. Figure P11-2 shows a one-line diagram of a simple power system. Assume that the generator G₁ is supplying a constant 13.8 kV at Bus 1, that load M₂ is consuming 20 MVA at 0.85 PF lagging, and that load M₃ is consuming 10 MVA at 0.90 PF leading. Calculate the bus admittance matrix Y_bus for this system, and then use it to determine the voltage at Bus 2 in this power system. (Note: assume that the system base apparent power is 30 MVA.)
