Abstract :
In this paper three control areas are considered, each area contains one hydro and one thermal system. All the three areas are connected with the help of HVDC link. Automatic Generation Control (AGC)problem formulation is affected with open transmission access and evaluation of more socialized companies for generation, transmission and distribution. Therefore conventional three area system is modified so that it will consider the effect of bilateral contract on dynamics. Dynamic analysis is carried out on three area hydrothermal system with HVDC link as well as with AC tie line. It is observed that dynamic response of three area hydro thermal system connected with AC tie line is sluggish and degraded compared with HVDC link.
