1. Consider the IEEE 14-bus system shown in Fig. 3.12. The bus data are presented in Table 3.5 and the branch data in Table 3.6 (values of P in MW, Q, and bsh in MVAr, magnitude of nodal voltage in Volts, and phase angle of nodal voltage ? in radians). With these data, following are requested: (a) Calculate the power flow of the IEEE 14-bus system. (b) Increase the powers P and Q of bus 13 by multiplying them by a factor of 1.5 and then multiplying them by 2 . Comment about the main changes observed. (c) Decrease the powers P and Q of bus 13 by dividing them by a factor of 1.5 and then dividing by 2.0 . Comment about the main changes observed. (d) Suppose lines 2-3 have been removed, what happens to the other lines connected to buses 2 and 3 ?
