Abstract: In this study, Flexible AC Transmission System (FACTS) devices are optimally located in a power network to maximize the system loadability. FACTS devices are used in transmission system to control the system performance. The location of FACTS devices and the setting of their control parameters are optimized by gbest Gravitational Search Algorithm (GGSA) to improve the performance of the power network. The FACTS devices namely SVC (Static VAR Compensator) and TCSC (Thyristor Controlled Series Compensator) is considered to maximize the system loadability. The proposed system is used to control the main parameters namely voltage, phase angle and impedance which is affecting AC power transmission. Proposed algorithm is tested on IEEE 30 bus system for optical location and sizing of multi type FACTS devices and the system loadability gets improved and the transmission line losses are reduced.
