This paper presents the Gravitational Search Algorithm (GSA) that can be used to determine Location of Thyristor controlled series capacitor in the electrical network. TCSC is equipment used to regulate and improve power flow in power system. Test results using the west algerian Power System showed that the optimal placement location of TCSC using this GSA method could reduce the active power and reactive power losses on the line as well as improve the value of the voltage to stay in standard limit of 0.95 ±1.05 pu. The results are quite encouraging and the algorithm is found to be simple and easy to implement
