The power system shown has the following parameters:
• Bus 1: Slack Bus: V= 1.05L0 pu
• Bus 2: PQ Bus: P= 2.566 pu and Q= 1.102 pu
• Bus 3: PQ Bus: P= 1.386 pu and Q= 0.452 pu
• Line impedances are in pu on 100 MVA base: Line 1-2: Y= 10-j20 pu, Line 2-3: Y= 16-j32
pu, Line 1-3: Y=10-j30 pu.
Solve the power flow problem (two iterations) and calculate the line losses (in MW and
MVAR) using:
a) Gauss-Seidel method.
b) Newton-Raphson method.
Part II:
Write a code with any programming language (Ex: MATLAB, C-language...etc.) which solve
the previous problem in both Gauss-Seidel and Newton-Raphson methods.
The solution should calculate the V, 8, P and Q at each busbar at steady state (Use your
engineering judgement to specify the number of iterations).
