Consider the electric power system shown {see attachment}. The power-flow solution of this system can be obtained without resorting to iterative techniques. The elements of the bus admittance matrix Ybus have been calculated as: {see attachment}.

Calculate the phase angle {see attachment} by using the real and reactive power equations at bus-3 (load bus).
