 In recent years, a number of Flexible AC Transmission system (FACTS) devices have been proposed for better utilization and enhancing the power transfer capability of existing power transmission network. There are several conventional methods to improve the voltage profile and annual savings, but FACTS devices are shown better results to improve transmission line performance such as power profile and annual savings. The ability to enhance power transfers lead to their applications in a multi machine power system for the purpose of an overall reduction in power generation cost, compared to others. This paper focus on the evolution of economic viability for reducing generation cost using FACTS devices. The most and versatile FACTS devices, such as Static Var Compensator (SVC), Thyristor Controlled Series Capacitor (TCSC) and Unified Power Flow Controller (UPFC) are used to improve transmission capacity of the system. The devices are incorporated in the system by the Optimal Power Flow method and Genetic Algorithm based optimization technique. The proposed methods are tested on IEEE-57 bus system and the corresponding test results are compared with conventional method.
