Abstract

This paper investigates the impact of Ultra High Voltage (UHV) transmission on the voltage stability of electric networks, and proposes remedial solutions. The proposed solution is based on using Flexible AC Transmission Technology (FACTS). A Static Var Compensator (SVC) is chosen as a low cost solution to replace a conventional capacitor bank, thus allowing a continuous and flexible nodal voltage adjustment and improve voltage control. The study compares the proposed FACTS to traditional compensators terms of voltage stability dynamic performances of the electric network.
