Abstract :
Experience with the transmission expansion planning of a longitudinal power system is reported. To reach an optimal choice among several feasible expansion plans, indices such as maximum power transfer limits, fault currents, transient stability, system losses, and cost, which have been widely used by utilities, are computed to compare the relative merits of these alternatives. In view of past experience with low-frequency oscillations taking place in the study system, oscillatory stability of the power system under each expansion plan is examined in detail by means of eigenvalue-eigenvector analyses. Recommendations are made with regard to future expansion plans on the basis of the present study
