<![CDATA[The increasing need for electrical energy in Indonesia causes the operational transmission network to experience stress to the limit of permissible stability. Changing the transmission line configuration can be used as a solution to this problem. Changes in transmission line configuration cause voltage stability problems on transmission lines. The main factors that cause voltage stability problems are: limits on generator reactive power, load characteristics, and characteristics of compensators installed on transmission lines. Increasing the voltage profile on transmission lines can be done by adding a Flexible Alternating Current Transmission System (FACTS) device. Determining the location and capacity of FACTS is a very important thing to take into account considering the relatively expensive investment costs for this equipment. TCSC is one of the simpler FACTS devices, and can be controlled easily compared to other FACTS equipment. The implementation of the League Championship Algorithm (LCA) algorithm in determining the optimal location for placing FACTS devices has been able to reduce power losses. Loading is carried out under normal conditions, loads of 125%, 140% and 150%. Several loading conditions on the IEEE 14 BUS system have shown voltage stability in conditions after FACTS installation.]]>
