Enhancing Power Quality in Three‐Phase Distribution Systems Using PV‐Supported DSTATCOM: A Simulation‐Based Study

The escalating demand for electricity underscores the critical need for stability in power systems. Distribution networks face formidable power quality challenges due to unregulated utilization of diverse loads, leading to voltage fluctuations, harmonics, and phase unbalance. This study employs a distribution static compensator (DSTATCOM) to mitigate harmonics and reactive currents in AC mains, addressing voltage challenges in three‐phase distribution systems. Integrating an unconventional energy source, represented by solar cells, directly with a static synchronous compensator enhances power quality. Simulation results demonstrate balanced and sinusoidal source currents, effectively regulating load voltage against supply variations. The proposed PV‐supported DSTATCOM system, explored through typhoon simulation, exhibits robust harmonics tracking even under unbalanced loads. Total harmonic distortions (THDs) of the compensated source current consistently remain below IEEE‐519 standards in all scenarios. The innovative system, combining photovoltaic support with DSTATCOM, holds promise for enhancing power quality in distribution networks. This study contributes valuable insights into applying PV‐supported DSTATCOM to address power quality challenges. The simulation‐validated performance showcases this approach’s efficacy, significantly contributing to the optimization of distribution systems and advancing the field of power quality control in photovoltaic systems.
