Abstract: This study presents an Efficient Genetic Algorithm (EGA) to solve the problem of optimal power flow with controllable FACTS devices. Two types of FACTS devices, Thyristor Controlled Series Compensator (TCSC) and Thyristor Controlled Phase Shifter (TCPS) are considered. The specified power flow control constraints due to the use of FACTS devices are included in the OPF problem in addition to the normal conventional constraints. The sensitivity analysis is carried out for the location of FACTS devices. In the solution process EGA is integrated with conventional OPF to select the best control parameters to minimize the total generation fuel cost and keep the power flows within the security limits. This method provides an enhanced economic solution with the use of controllable FACTS devices. Advanced and problem-Specific operators are introduced in order to enhance the algorithm�s efficiency and accuracy. The probabilities of crossover and mutation are varied by adaptive algorithm. The effectiveness of the proposed method is demonstrated on IEEE 30-bus system.
