Power Quality Enhancement of Utility-Distribution System Using Reduced-Switch PV-DSTATCOM Based on Modified Unit Template Technique

This paper describes a three-phase Voltage Source Converter (VSC) based 4-switch grid-tied DSTATCOM using new Modified Unit Template Technique to achieve power quality improvement. The system under test is
$3 \Phi$
−3W power system to which at PCC PV-DSTATCOM is connected. The DC-Link Voltage is kept stable and voltage balancing is achieved across the split capacitors under the loading conditions. Maximum Power Point Tracking (MPPT) operated by Perturb and Observe Algorithm is used to provide the fixed power which is trapped and transformed from the PV-Array to the boost converter circuit. The model is developed in MATALB and RT-LAB software in Real-Time having Computation and Communication blocks for synchronization with OPAL-RT 4510 and to it a four-channel oscilloscope (RIGOL-MSO5204) is connected for display of the results.
