Abstract
Electrical power quality (EPQ) in distribution systems is a critical issue for commercial, industrial and residential applications. The new concept of advanced power electronic based Custom Power Devices (CPDs) mainly distributed static synchronous compensator (D-STATCOM), dynamic voltage restorer (DVR) and unified power quality conditioner (UPQC) have been developed due to lacking the performance of traditional compensating devices to minimize power quality disturbances. This paper presents a comprehensive review on D-STATCOM, DVR and UPQC to solve the electrical power quality problems of the distribution networks. This is intended to present a broad overview of the various possible DSTATCOM, DVR and UPQC configurations for single-phase (two wire) and three-phase (three-wire and four-wire) networks and control strategies for the compensation of various power quality disturbances. Apart from this, comprehensive explanation, comparison, and discussion on D-STATCOM, DVR, and UPQC are presented. This paper is aimed to explore a broad prospective on the status of D-STATCOMs, DVRs, and UPQCs to researchers, engineers and the community dealing with the power quality enhancement. A classified list of some latest research publications on the topic is also appended for a quick reference.
Highlights
Nowadays electrical power quality is a very important issue in the electrical distribution system
This paper focuses on a DSTATCOM, dynamic voltage restorer (DVR) and unified power quality conditioner (UPQC) type compensating custom power devices
The custom power devices (CPDs) mainly DSTATCOMs, DVRs and UPQCs are the active power filters (APFs) family members connected in shunt, series and a combination of shunt and series to achieve superior control over different power quality disturbances simultaneously
Summary
Nowadays electrical power quality is a very important issue in the electrical distribution system. The compensating custom power devices are used for active filtering, load balancing, voltage regulating (sag/swell), harmonic elimination and power factor correction. These devices are either connected in shunt or in series or a combination of both and called D-STATCOM, DVR and UPQC. DVR: A dynamic voltage restorer (DVR) is a power electronic (PE) converter-based CPD, which can protect sensitive loads from all supply-side disturbances other than outages The different aspects such as modeling, design and simulation for harmonic elimination, voltage flicker suspension [9], voltage sag and swell mitigation are reported in [51,52,53,54]. A.Ghosh et al [65] discussed the application of UPQC for voltage regulation in critical loads
