This article provides the application of several methodologies to obtain power transmission limits through interties of the electric power systems to obtain a secure operation of the energy power system. Several aspects to obtain the maximum power flows of electrical energy thought of transmission lines on electrical grids are shown. Thermal limit of electrical conductors, loadability limit of transmission lines and small signal stability limits are obtained for several interties between geographical regions. It also, shows the application of a load shedding scheme to stabilize an interarea oscillation mode. The model of the Mexican Interconnected power System is used to illustrate these methodologies.

Keywords : transmission limits; thermal limit; loadability of lines; small signal oscillation limit.
