a) Explain the disadvantages of the Gauss-Seidel method, what is the alternative solution? V = 1 p.u. P=0.6 p.u. V= 1 p.u. Slack j0.2 p.u. j0.05 p.u. jo.025 p.u. (0.8 + j0.6) p.u. b) Set up the impedance matrix for the ring network in the figure above. All listed p.u. values have common base values. c) Determine the voltage at busbar (2), the voltage on busbar (3) and the reactive power on busbar (3) as shown in the figure above, following the first iteration of a Gauss-Seidel load flow method. Assume that the initial voltage of all bus rails is V = 120° p.u. a) Explain the disadvantages of the Gauss-Seidel method, what is the alternative solution? V = 1 p.u. P=0.6 p.u. V= 1 p.u.
