Abstract –When electrical energy is transmitted from generation plants to users through transmission and distribution networks, energy and power losses occur, due to the physical characteristics of the network components. These losses are inherent in the conduction of electrical energy through physical means and cannot be completely avoided. There are significant opportunities to improve the energy efficiency of existing networks and future extensions. Improving efficiency means implementing measures that take levels of effectiveness beyond accepted practices for the activity. There are a number of practical measures and technologies that can be implemented to reduce network losses. This paper presents a power loss minimization framework for TCSC (Thyristor Controlled Series Compensator) with the use of metaheuristic methods used to minimize the power loss. Particle Swarm Optimization (PSO) and Salp Swarm Algorithm (SSA) are used to find the optimal location of TCSC for IEEE-14, IEEE-33, and IEEE-57 bus test systems. Performance analysis is done on the basis of active and reactive power losses.
