Abstract-This paper examines the performance of a STATCOM in improving power quality and balancing network operations in the distributed energy sector. It explores the structure and characteristics of STATCOMs, emphasizing their role in maintaining balanced network operations through reactive power generation. Additionally, the study delves into the significance of Pulse Width Modulation in enhancing device efficiency and showcases its advantages. A novel hybrid D-STATCOM topology is proposed to address unbalanced and nonlinear loads in distribution systems, aiming to improve power transmission efficiency by utilizing Cascaded-H-Bridge and other complementary methodologies. The paper also discusses control strategies and simulation operations using MATLAB, providing insights into practical implementation for enhanced grid stability and power quality enhancements. By using Cascaded H-Bridge D-STATCOM topology total harmonic distortion in the currents has been decreased to 0.9%.
