Mitigating power quality issues in distribution systems is of utmost importance to both electricity consumers and suppliers as it improves the distribution system's efficiency, reduces electricity costs, maintains continuous supply, and diminishes the requirement for frequent maintenance. Custom power devices were introduced to eliminate power quality issues like voltage sags, swells, transients, imbalances, and current harmonics arising in distribution systems. Unified power quality conditioner (UPQC) is one such frequently used custom power device that enhances the power quality of distribution systems. Various structural arrangements of UPQCs with improved performance capability were introduced within the last few decades. The main aim of this paper is to review the most frequently explored UPQC models in literature and to observe the impact of these UPQC structural configurations on their performance as well as that of the overall distribution system. Also, this study investigates the properties, applications, and control techniques used by these structural configurations of UPQCs to mitigate power quality issues.

The power system is facing numerous issues when the distributed generation is added to the existing system. The existing power system has not been planned with flawless power quality control. These restrictions in the power transmission generation system are compensated by the use of devices such as the Static Synchronous Compensator (STATCOM), the Unified Power Quality Conditioner (UPQC) series/shunt compensators, etc. In this work, UPQC's plan with the joint activity of photovoltaic (PV) exhibits is proposed. The proposed system is made out of series and shunt regulators and PV. A boost converter connects the DC link to the PV source, allowing it to compensate for voltage sags, swells, voltage interferences, harmonics, and reactive power issues. In this paper, the features of a seven-level Cascaded H-Bridge Multi-Level idea are applied to shunt and series active filter changeovers to reduce Total Harmonic Distortion and compensate for voltage issues. Despite its power quality capacity for common coupling, the proposed system can inject the grid's dynamic power. During voltage interference, it can also provide a piece of delicate burden power. The simulation is carried out with the help of MATLAB/SIMULINK programming, and the results are compared to those of other conventional methods.

“…The features and capability of the MAB converter have made it a suitable candidate for a wide range of applications and it has gained the interest of many researchers. MAB converters with different numbers of ports and their combination with other converters have been proposed for the following applications: hybrid energy storage (HESS) [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]; more electric aircraft (MEA) [19][20][21][22][23][24][25]; monopolar and bipolar DC grids [26][27][28][29][30][31][32][33][34]; Solid state transformer (SST) and modular transformer in microgrids, locomotive traction, EV charging, shipboards ; doubly fed induction generators (DFIG) in wind turbines [58]; unified power quality conditioner (UPQC) [59][60][61][62]; electric vehicle (EV) charging [63][64][65][66][67]; renewable energy systems (RES) such as PV modules integration with energy storage systems (ESS), microgrids or EV charging stations [68][69]…”

“…Since a three-port MAB converter or triple active bridge (TAB) converter can meet the requirements in many applications, it is the most explored type of MAB converter [77]. However, depending on the application, adding more active bridges to achieve a higher number of ports has been proposed, resulting in the quadruple active bridge (QAB) [12,17,23,39,40,43,[46][47][48][49]51,52,[54][55][56][60][61][62]70,[78][79][80][81][82][83][84][85][86][87][88][89][90], penta active bridge (PAB) [41], 6-port [91], 10-port [75], and 12-port [35,92,93] MAB converters. Although adding more ports can provide potential advantages over the DAB converter, converter analysis becomes more complicated, and a research gap arises between the conventional DAB and the various MAB converters.…”

Multi-port DC-DC converters are a promising solution for a wide range of applications involving multiple DC sources, storage elements, and loads. Multi-active bridge (MAB) converters have attracted the interest of researchers over the past two decades due to their potential advantages such as high power density, high transfer ratio, and galvanic isolation, for example, compared to other solutions. However, the coupled power flow nature of MAB converters makes their control implementation difficult, and due to the multi-input, multi-output (MIMO) structure of their control systems, a decoupling control strategy must be designed. Various control and topology-level strategies are proposed to mitigate the coupling effect. This paper discusses the operating principles, applications, methods for analyzing power flow, advanced modulation techniques, and small signal modelling of the MAB converter. Having explained the origin of cross-coupling, the existing power flow decoupling methods are reviewed, categorized, and compared in terms of effectiveness and implementation complexity.
