Question

For the three bus power system whose YBus is given, calculate the solution of the power systems using the Newton-Raphson method. Assume bus 1 as the slack bus with V1=1.0∠0o and buses 2 and 3 are load buses with a per unit load of S2=1.7+j0.75 and S3= 1.8+j0.5. Use voltage guesses of 1.0∠0o at both buses 2 and 3. YBus: Y11= Y22=Y33=-j9,Y12=Y13=Y21=Y23=Y31=Y32=j5. Perform two iterations. Repeat question 3 with Fast Decoupled and Decoupled load flow methods and compare the results with the Newton Raphson Method.
