Abstract :
This paper addresses the evaluation of total transfer capability in hydro-dominated power systems focusing on the Brazilian interconnected power systems. The methodology currently adopted by the Brazilian national system operator to compute transfer limits is presented. A methodology that automatically integrates optimal power flow, transient, small-signal and voltage stability simulation is also discussed. Results obtained with the techniques described are presented.
