Illustrations:
transmission line data
the first number succeeding the above line is the total number of lines,
the line
data follows the following order:
from_bus, to_bus, resistance, reactance, total susceptance
shunt capacitor
the first number succeeding the above line is the total number of
capacitors,
bus, susceptance

Problem 1 (40 points). A network's components and parameters are described in the text file EE536 NW2.txt. Develop a program to build the bus admittance matrix. You can use Matlab The diagram is shown in the following figure. The value shown refers to impedance for series branches and admittance for shunt capacitors. 10.1+j0.2 2) 0.3+j0.4 j0.05 (0.01/2)j (0.01/2)j 0.2+j0.6 4 j0.1 Please submit both your Matlab program and the final result of the bus admittance matrix

Explanation / Answer
