⦁For the power system shown in Figure 1 with input data given in Table I, draw the per-phase per unit equivalent circuit. Assume a three-phase 100 MVA per unit base. Determine the bus admittance matrix (Ybus). When Bus 1 is slack bus and bus 2 a voltage-controlled bus, find the unknown the presentation of vector x, known vector y, the initial Jacobian matrix in Newton-Raphson method and the J1 and J4 matrix for fast decoupled method of power flow analysis.
