Consider the system shown in the figure. Assume a 100 MVAbase.

a) Compute the Ybus matrix.
b) Calculate the bus voltages for the first two iterationsanalytically.
c) Use MATLAB redo the question. Compare the result with a) andb)
The bus specifications and the line impedances are given in thetables. The reactive power constraint of bus 2 is, 0.4 <= Q2<= 1.0 pu.
4 Bus specifications-all values are injected power in per unit Bus cod<e Remarks Slack bus
