The Flexible AC Transmission System (FACTS) controllers have been resolved many technical issues which emerged with deregulated environment. One of such issues is transmission system performance improvement under open access. In this paper, two FACTS controllers, Thyristor-Switched Series Capacitor (TSSC) and Unified Power Flow Controller (UPFC) are selected to improve the system performance. At the first stage, the generation schedule under competitive electricity market dispatch model is obtained and at the second stage, the impact of the selected FACTS controllers is analyzed while executing various power transactions. A two-stage hybrid optimization approach using Gravitational Search Algorithm (GSA) and Particle Swarm Optimization (PSO) algorithm is adopted to find out the optimal location and parameters of FACTS controller to achieve the required objectives like voltage stability index maximization as well as transmission loss minimization. For case studies, standard IEEE 30 bus test system is used and the simulation results obtained have been validating for real-time adaptability of this proposed method.
