1. The below given Figure shows the one-line diagram of a simple three-bus power system with generation at buses 1 and 3. The voltage at bus 1 is $V_1 = 1.025\angle0^\circ$ per unit. Voltage magnitude at bus 3 is fixed at 1.03 pu with a real and reactive power generation of 2mn MW, 9m.n MVar, respectively. A load consisting of 400 MW and 200 MVar is taken from bus 2. Line admitances are marked in per unit on a 100 MVA base. For the purpose of hand calculations, line resistances and line charging susceptances are neglected. Using Gauss-Seidel method and initial estimates of $V_2^{(0)} = 1 + j0$ pu and $V_3^{(0)} = 1.03 + j0$ and keeping $|V_3| = 1.03$ pu, determine the phasor values of $V_2$ and $V_3$. Perform three iterations. (50p) $V_1 = 1.025 + 0j$ 1 y13 = -20j $|V_3| = 1.03$ 3 2mn MW 9m.n MVar y12 = -40j 400MW 2 y23 = -40j 200 MVar m = 0 n = 7 I need only matlab code for this question.

Speed Co. is an established recreation boat dealer. Their service center provides all scheduled maintenance services at no additional charge for any customer who purchases a boat and for as long as that customer owns the boat. The customer also may choose to have the maintenance services performed by others dealership. Neither Speed Co. nor any other dealer sells the boat without the same type of lifetime maintenance services. However, for customers who did not purchase their boat from Speed Co, they can purchase the maintenance services separately. The boats are sold subject to a limited warranty and there are no refund rights in the arrangement. Comment on the unit of accounting for the automobile and the maintenance services
