Question

The figure shows system having two plants 1 and 2 connected to buses 1 and 2,
respectively. There are two loads and a network of three branches. The bus 1 is
the reference bus with voltage of 1.0 pu. The branch currents and impedances
are: la=2-j0.5 p.u; lb=1.6-j0.4 p.u; Ic=1.8-j0.45 p.u;Za=0.06+j0.24 p.u;
Zb=0.03+jO.12 p.u; Zc=0.03+j0.12 p.u; Calculate the loss formula coefficients of
the system in per unit. Calculate the system loss.
