Multilevel Inverter STATCOM based Distribution Network for Power Quality Improvement

Abstract

This paper investigates the implementation of a Five-Level Multilevel Inverter (MLI) based Static Synchronous
Compensator (STATCOM) for enhancing power quality in distribution networks. The proposed STATCOM
configuration employs advanced control strategies to efficiently manage reactive power flow, thereby stabilizing
voltage levels and minimizing power quality issues such as voltage sags, swells, and harmonic distortions.
Utilizing a MATLAB/Simulink environment, the design and operation of the five-level MLI STATCOM are
modeled and simulated, highlighting its effectiveness in improving the power factor, reducing Total Harmonic
Distortion (THD), and ensuring robust voltage regulation across the distribution network. The simulation results
demonstrate the superior performance of the proposed STATCOM in addressing a wide range of power quality
challenges, making it a viable solution for modern electrical distribution systems facing the integration of
renewable energy sources and fluctuating loads. This study contributes to the advancement of STATCOM
technologies for better power quality management and enhanced grid stability.
