Abstract: Abstract In this paper, a solution is provided for solving optimal reactive power dispatch (ORPD) problem by using flexible alternating current transmission (FACTS) devices. The TLBO method is applied on IEEE 14-, 30- and 57- bus test system with optimal positioning of thyristor-controlled series compensator (TCSC) and static var compensator (SVC). The location for TCSC and SVC has been chosen by performing power flow analysis. The ORPD problem is formulated to minimize both active power loss and operating cost. The main objective of this work is to dispatch optimal reactive power considering various loading conditions. The performance of the proposed method is tested under increased reactive loading and simultaneous increased of both active and reactive loading conditions. The proposed method's performance is evaluated under various operating conditions. The obtained results are compared with some of the recent promising techniques such as KHA, BBO and PSO. The simulation results show the efficacy of the proposed method in achieving the better performance of the system in terms of minimum power loss, minimum operating cost and better convergence rate.
