The major problem in grid-connected power transmission and distribution networks is the quality issues due to the unbalance loads. The power quality issues related to the current and voltage-based issues generated at the PCC (point of common coupling). Some of the current issues related to reactive power extraction, poor zero voltage regulation, harmonic currents, undesired neutral current, and low power factor. Several D-STATCOM compensation techniques have been introduced for the compensation of power quality issues in the three-phase and four-wire system. The proposed work focuses on...
