Repeat Problem 6.42 except with the bus 2 real power load changed to 1.0 per unit.

Data From Problem 6.42:-

Use the Newton-Raphson power flow to solve the power system described in Problem 6.34. For convergence criteria use a maximum power flow mismatch of 0.1 MVA.

Data From Problem 6.34:-

For the three bus system whose \(Y_{\text {bus }}\) is given below, calculate the second iteration value of \(V_{3}\) using the Gauss-Seidel method. Assume bus 1 as the slack (with \(V_{1}=1.0\left(0^{\circ}\right)\), and buses 2 and 3 are load buses with a per unit load of \(S_{2}=1+j 0.5\) and \(S_{3}=1.5+j 0.75\). Use voltage guesses of \(1.0 / 0^{\circ}\) at both buses 2 and 3 . The bus admittance matrix for a three-bus system is

\[
\mathrm{Y}_{\text {bus }}=\left[\begin{array}{ccc}
-j 10 & j 5 & j 5 \\
j 5 & -j 10 & j 5 \\
j 5 & j 2 & -j 10
\end{array}\right]
\]
