“…The most popular form of pulse width modulation (PWM) synthesis is the sinusoidal pulse width modulation (S-PWM) [20], [47], [77], [80][81][82], [107], [111], [112], [117], [125], [126], [130], [203], [205], [207]. In an S-PWM scheme the modulating signal is sinusoidal and carrier signal is a triangular wave.…”

“…Single-phase two-wire (1p2w) systems are used in all three modes as shunt (D-STATCOM) [71][72][73][74], series DVR [75][76][77][78][79][80][81][82][83] and a union of both as UPQC [84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101]. 215 Figure 9 (a-c) shows the most popular DSTATCOM, DVR and UPQC configurations consist of two H-bridge inverters [72][73][74], [83], [84], [86][87][88][89][90][91][92][93][94][95][96][97], [99], …”

“…The synchronous reference frame (SRF) theory is developed in time-domain based reference current/voltage generation technique. The SRFT is performing the operation in steady-state or transient state as well as for generic voltage and current and capable of controlling the active power filters in real time system [15] , [18], [20], [21], [27], [28], [51], [54], [57], [58], [76], [77], [82], [104], [106], [111], [115], [120], [121], [125], [127], [128], [130], [131], [133], [134], [137], [141], [142], [150], [153], [155], [160], [167], [177], [178], [179], [180], [182], [187], [189], [190], [195], [204], [203], [207],…”

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.
