Enhancing Electric Power Quality Using UPQC: A Comprehensive Overview

TLDR

Researchers have used varying names for UPQC depending on its function, task, application, or topology. This review aims to provide a comprehensive overview of UPQC configurations, compensation approaches, and recent developments for single‑phase and three‑phase distribution networks. The authors catalog 12 UPQC acronyms derived from a systematic review of over 150 papers, classifying them by configuration and function. The study presents an acronymic list that distinguishes UPQC variants and classifies more than 150 related papers, highlighting their unique features.

Abstract

This paper presents a comprehensive review on the unified power quality conditioner (UPQC) to enhance the electric power quality at distribution levels. This is intended to present a broad overview on the different possible UPQC system configurations for single-phase (two-wire) and three-phase (three-wire and four-wire) networks, different compensation approaches, and recent developments in the field. It is noticed that several researchers have used different names for the UPQC based on the unique function, task, application, or topology under consideration. Therefore, an acronymic list is developed and presented to highlight the distinguishing feature offered by a particular UPQC. In all 12 acronyms are listed, namely, UPQC-D, UPQC-DG, UPQC-I, UPQC-L, UPQC-MC, UPQC-MD, UPQC-ML, UPQC-P, UPQC-Q, UPQC-R, UPQC-S, and UPQC-VA. More than 150 papers on the topic are rigorously studied and meticulously classified to form these acronyms and are discussed in the paper.
