Power system is growing massively with rapid increasing load demand by consumer. Load growth and contingency in power system cause an insufficient real power that leads to high-power losses. FACTS device is the latest power electronics controller by which power losses can be reduced and transfer capability can be enhanced. This study is to decide the best location to install these devices in considering to its cost installation which is it quite expensive. The main objective of this study is to determine the optimal location and sizing for TCSC and STATCOM by introducing Loss Sensitivity Factor as analytical method to minimize power losses in the system. Results have been obtained by determining the location of weak lines for TCSC integration and weak buses for STATCOM integration utilizing the proposed technique which aimed to improve overall system’s losses in the benchmark system. The proposed approach has been implemented in IEEE 14 Bus test system which is modelled and simulated using DigSILENT PowerFactory 18. This proposed technique has shown a remarkable performance to keep the system at the lowest power losses in different given scenarios
