Enhancing Power Quality in DC Systems with a Multilevel Cascade Converter Utilizing UPFC Technology

Abstract

This paper presents a comprehensive study on the development and implementation of a multilevel cascade converter designed to enhance power quality in DC systems through the integration of a Unified Power Flow Controller (UPFC). As the demand for efficient and reliable power systems continues to rise, addressing power quality issues such as voltage fluctuations, harmonics, and transient disturbances becomes increasingly critical. The proposed multilevel cascade converter leverages advanced control strategies and topologies to improve voltage regulation, reduce harmonics, and enhance overall system stability. By incorporating UPFC technology, the converter can dynamically manage power flow, enabling real-time adjustments to meet varying load conditions and enhance the reliability of the DC system. Simulation results demonstrate the effectiveness of the multilevel cascade converter in mitigating power quality disturbances, achieving significant improvements in performance metrics. This research not only contributes to the understanding of power quality enhancement techniques but also paves the way for more robust and efficient DC power systems. The findings emphasize the potential of integrating multilevel converter technology with UPFC to address the challenges posed by modern electrical grids, ultimately supporting the transition towards more sustainable and reliable energy solutions..
