Flexible Alternating Current Transmission Systems (FACTS) devices have been proposed as an effective solution for controlling power flow and regulating bus voltage in electrical power systems, resulting in an increased transfer capability, low system losses, and improve stability. However, to what extent the performance of FACTS devices can be brought out highly depends upon the location and the parameters of these devices. The design uses three optimization algorithm i.e. Gravitational Search Algorithm (GSA),Grey Wolf Algorithm(GWA) and Firefly Algorithm(FA).The main objective of this work is to determine the optimal location and the optimal parameter setting of the Thyristor Controlled Series Compensator (TCSC) in the power network to minimize the loss of the power system and compare their performances. To show the validity of the proposed techniques and for comparison purposes, simulations are carried out on IEEE-57 bus power system. The results are presented in the simulation video demo as given below.
