Design and Comparative Analysis of Shunt-Passive and Series-Passive for AC Drives-based Loads using Sequential Quadratic Programming

This study uses Sequential Quadratic Programming (SQP) as an optimization technique. Shunt-passive and series-passive filters have been investigated to reduce the harmonic distortion associated with AC drive loads while accounting for utility source and load non-linearities. DC drives represented by their equivalent current source model are much more common in practice. On the opposite side, AC drives are also possible, and they are indicated by their corresponding voltage source model. The performance of the filters for these non-linear loads under different scenarios is compared. It was discovered that the type of non-linear load significantly limits the selection of a suitable compensator.

I. Introduction

The control of harmonics has grown in significance in recent years for several reasons. The number of nonlinear loads in the commercial, residential, and industrial domains has led to an increase in harmonic-related issues. Harmonic currents are introduced into the power system by nonlinear loads such as variable speed drives and power electronics. These harmonic currents can lead to premature equipment failure, equipment malfunctions, and distortions of the voltage and current waveforms. Furthermore, integrating renewable energy sources—like solar and wind—has highlighted the necessity of efficient harmonics management to guarantee the seamless integration of these sporadic energy sources without sacrificing power quality. Compliance with the stringent rules and guidelines established by authorities and oversight organizations is also essential to stay out of trouble and keep things running smoothly. Harmonics can also disrupt data transfer, telecommunication networks, and wireless communication by interfering with communication systems. Thus, harmonics management is crucial to reducing power quality problems, safeguarding machinery, facilitating the integration of renewable energy sources, and maintaining dependable communication systems in contemporary power systems across several industries [1]–[4].
