Transmission expansion planning state of the art

Abstract

In this paper the transmission expansion plannig aproaches are presented. These approaches are classified according to the structure of the power system, to the planning horizon and to the uncertainties of the power system. Transmission Expansion Planning has faced a significant change since the introduction of the deregulation; consequently it has become to be more complicated. The algorithms that have been developed to solve the problem of the planning in regulated and deregulated power systems are presented. Finally, it is presented the evolution and the planning schemes in several countries of Latin America.
