An Overview of Placement of TCSC for Enhancement of Power System Stability

Flexible Alternating Current Transmission Systems (FACTS) represents a vast development in the area of power system operation and control. This paper gives an overview about application of series connected Flexible alternating current transmission system (FACTS) for enhancement of power system performance like transfer stability, secure voltage profile and reduce the system losses etc. FACTS devices require huge capital investment. Therefore, heuristic techniques are used for optimal location and sizing of series FACTS controllers like Genetic Algorithm (GA), Particle Swarm Optimization (PSO) etc. This paper gives details of optimal placement and sizing of FACTS devices based on different evolutionary techniques which is used for minimization of transmission loss, enhancement of stability of power system. In this study one of the FACTS devices is used as a scheme for enhancement of power system stability. Proper installation of FACTS devices also results in significant reduction of transmission loss. In this review, TCSC is selected as the compensation device.
