Power Loss Reduction in Transmission Systems Using PSO-Based Static Var Compensator Optimization

Abstract

The increasing demand for electrical energy has resulted in higher loading of transmission lines, which often leads to increased power losses and reduced system efficiency. One of the effective solutions to mitigate these problems is the implementation of reactive power compensation using Static Var Compensators (SVC). However, the optimal placement and sizing of SVC units play a crucial role in achieving significant loss reduction. This study proposes the use of Particle Swarm Optimization (PSO) to determine the optimal location and capacity of SVC in a transmission network. The optimization process aims to minimize real power losses while maintaining voltage stability and improving overall system performance. Simulation is carried out on a standard IEEE test bus system, and the results demonstrate that the proposed PSO-based SVC allocation significantly reduces transmission losses compared to conventional methods. The findings highlight the potential of intelligent optimization techniques in enhancing the efficiency and reliability of modern power transmission systems.
