Three phase four wire distribution static compensator for power quality improvement.

Poor voltage control, high reactive power demand, harmonics in source current, load imbalance, excessive neutral current, etc. are power quality issues that affect three-phase, four-wire distribution systems. As a result, neutral current is excessively present at fundamental and harmonic frequencies. This work explores the use of PI and ANN controllers for PQ theory to enhance the functioning of DSTATCOM and enhance power quality. The instantaneous reactive power theory (PQ theory) with PI and ANN controllers is investigated using the MATLAB environment. The simulation's outcome demonstrates how successfully the DSTATCOM controlling approach worked. [ABSTRACT FROM AUTHOR]
