Abstract

For the efficient transmission of power from power plants to consumer loads, the power losses are reduced and voltage profiles are improved in modern power system. In order to reduce such losses and improve voltage levels , a recently evolved FACTS technology is used. In this paper, Thyristor Controlled Series Capacitor (TCSC) is selected to enhance the load ability in the transmission line. This paper presents a new approach on modeling of the device by changing the firing angle of the power electronic device of the FACTS device. This is done by using Hybrid GA-PSO and DA-PSO which is participated to finalize the best location of the TCSC device and optimal firing angle of the TCSC. The location of the device is optimized by either GA or DA and the optimized firing angle is done with PSO algorithm. Because of the two different Optimizing techniques are used to solve single objective function. This type of optimization is called Hybrid optimization. The proposed hybrid optimization method is an effective method for finding the optimal location of TCSC device and also for enhancing the voltage profiles of the line and reducing the power system losses. This hybrid GA-PSO and DA-PSO is tested on IEEE 57 test system and simulation results are presented.
