The electricity demands and transactions in power markets increase frequently. Hence existing power networks must be enhanced for better utilization. In this work, Artificial Bee Colony Algorithm (ABC) is proposed for enhancing and controlling power flow using Flexible AC Transmission System (FACTS) controllers. The objectives considered are enhancement of system loadability, reduction of Installation cost of devices and reduction of transmission loss. Three types of FACTS devices such as Static VAR Compensator (SVC), Thyristor Controlled Series Compensator (TCSC) and Unified Power Flow Controller (UPFC) are used. The optimal location and parameter setting of FACTS devices is achieved using ABC algorithm. In this paper two casesare considered: i) single type i.e. same type of FACTS device, and ii) multi type i.e. combination of SVC, TCSC, UPFC. The proposed algorithm is implemented on 6 bus, IEEE 30, IEEE 57 and IEEE 118 bus systems using MATLAB platform. The power flows are analyzed. The results obtained are compared with existing literature. The results indicate that the proposed algorithm gives better improvement in system loadability, reduction of transmission loss and installation cost. Hence the proposed algorithm will be useful in restructuring power networks.
