Improvement in frequency regulation of interconnected thermal power system with optimal SSSC and SMES controllers

Abstract

The level of real and reactive power reserve with only contribution from rotor inertia of generators provides a very small margin of maneuverability in system operation. The use of energy storage device and “Flexible AC Transmission systems (FACTs)” devices solves the problem to a large extent particularly in larger interconnected system. In this work energy storage devices like “Superconducting Magnetic Energy Storage (SMES)” system and “Static Synchronous Series Compensator (SSSC)”, are operated together in different combined two-area thermal system.
