Please solve all parts. Part 2 is done by Newton-Raphson, not Gauss-Seidel.
- Use Sbase=150 MVA. Bus no. 1 is the swing bus with V=1.058 p.u. and V=1.03 p.u.
- Use the following initial guesses for bus no. 2, 3, and 4: V=1.022 p.u. and V=1.073 p.u.
- Solve using Newton-Raphson Method. Make sure to do the following:
1. Construct the [Ybus] in rectangular and polar-degree form.
2. Perform two iterations and keep five decimal places.
- S=175+j90 MVA
- Swing?
- Z=0.004+j0.06 p.u. Total charging Mvar 7.8
- Z=0.006+j0.03 p.u. Total charging Mvar 8.6
- Z=0.004+j0.05 p.u. Total charging Mvar 13.2
- Z=0.002+j0.03 p.u. Total charging Mvar 9.4
- S=200+j55 MVA
- P=220 MW S=120+j70 MVA
