Consider a two-bus system with the single-line diagram diagram shown in Figure 1. In the two bus system, Bus 1 is slack bus where voltage is given in Fig. 1. Bus 2 is a PQ bus where load power is given. The impedance of the transmission between bus 1 and bus 2 is z₁₂= 0.0 + j0.20 p.u. Code computer programme using Newton-Raphson method to calculate power flow solution, using a convergence tolerance of _p=10^-6 : max | V_i^K+1 - V_i^K | _p

 

Bus 1 Bus 2 Z12 = 0.0 + jO.20 p.u. V, = 1.06 + j0.0 p.u. Pdz + jQdz = 0.80+jO.10 p.u.
