Comparison of control strategies for DSTATCOM in three-phase, four-wire distribution system for power quality improvement under various source voltage and load conditions

► Power quality improvement in three-phase, four-wire distribution system using DSTACOM. ► Proposed control strategy for DSTATCOM with IEEE standard-1459 power definitions. ► Linear/nonlinear load under ideal, unbalanced and distorted source voltage conditions. ► Reactive power compensation, source neutral current elimination, load balancing. ► Zero-sequence power compensation, harmonic mitigation as per IEEE-519 standard.
