You are given the four-bus problem as follows (Figure 6.34): The data for this problem are as follows:
x12 = 0.2;x14 = 0.4;x13 = 0.25;x24 = 0.5;x34 = 0.1;
Form the 4 × 4 Bx matrix for this network. Use of Matlab is
strongly recommended.
The first row will be
Bx = (1/ x12+1/ x13+1/ x14)−1/ x12−1/ x13−1/ x14
You cannot invert the Bx matrix, so you should replace all elements in the fourth column by zeros, and replace all elements in the fourth row by zeros. Now replace the term Bx(4,4) by 1.0 and the matrix can be inverted. The result,
which we shall call the X matrix, will be a 3 × 3 matrix corresponding to the first three rows and columns and the fourth row and column unchanged.
c. The generation and load on the system are
Pgen on bus 1=100.00 MWPgen on bus 2=150.00 MW
Pload on bus 3 = 350.00 MW
Assuming bus 4 as the reference, let theta for bus 4 be 0.0
radians.
Assume Sbase is 100 MVA.
d. You are going to solve a DC or linear power flow for this system. First con- vert all Pgen and Pload values to per unit, then solve for the bus phase angles on buses 1, 2, and 3. Then solve for the line flows on all transmission lines.

The six-bus system shown in Figure 1 will be simulated using MATLAB. Transmission line data and bus data are given in Tables 1 and 2 respectively. The transmission line data are calculated on 100 MVA base and 230 (line-to-line) kV base for generator. Tasks: 1. Determine the network admittance matrix Y 2. Find the load flow solution using Gauss-Seidel/Newton Raphson method until first iteration by manual calculation. Use Maltab software to solve power flow problem using Gauss-Seidel method. Find the...
