“…With the rapid spread of non-linear loads, they have become the primary reason for harmonic distortion in-branch currents, which, in due course, leads to harmonic voltage distortion at distribution system nodes/buses. Voltage sag, a severe PQ degradation, is an immediate or drastic drop in the root-mean-square (RMS) voltage value spanning from 0.1 to 0.9 per-unit and sustains within this abnormal drop from 0.5 cycles to a couple of seconds [6]. Voltage sags that last less than a 0.5 cycle duration are considered transients.…”

“…Static synchronous compensator (STATCOM) and unified power quality conditioner (UPQC) are fast response power-electronics-based FACTS installed in the SG to mitigate the unfavourable PQ disturbances such as voltage fluctuations, sag, swell, and harmonics. Authors in [4], [6], [18]- [20] did not discuss the comparison of FACTS such as STATCOM and UPQC with each other, especially in SGs. They did not give a detailed study or solutions to all the problems facing smart grids combined with renewable energy sources.…”

Power quality (PQ) assurance is a vital part of electrical distribution networks. There are many advantages and benefits of improving PQ, especially in the modern/smart grid. Smart grid (SG) has a lot of complicated and sensitive electrical components (non-linear loads) in addition to renewable energy systems (wind-solar) that may also be a source of PQ disturbances. PQ problems harm personal life and national production. Static synchronous compensator (STATCOM) and unified power quality conditioner (UPQC) are among the fastest response flexible alternating current transmission systems (FACTS) installed in smart grids to mitigate power quality disturbances such as voltage fluctuations, sag, swell, and harmonics. In this research, STATCOM and UPQC are designed and simulated in MATLAB/Simulink to overcome PQ-related disruptions in smart grids. Accordingly, the differences between the proposed two solutions are highlighted across this research and renewable energy sources' reliability during faults. Therefore, the reader will be able to choose the appropriate FACTS devices. This study emphasizes the extent of the smart grid need for the FACTS. As per the given results of this study, STATCOM and UPQC have shown exemplary performance in the PQ improvement investigations conducted in the context of smart/modern grids.

“…The impacts of power quality problems are voltage surges/spikes, voltage dips, under voltage, high-voltage spikes, frequency variation, power sag, electrical line noise, brownouts, blackouts, very short interruptions, long interruptions, voltage swell and harmonic distortion. (Jolhe et al , 2016; Wang et al , 2017). As per Indian Electrical Electronics Manufacturer Association (IEEMA) article (IEEMA, 2012 Article Electromagnetic Compatibility Power Electronics n.d.), Sag is the serious and major problem among all other power quality issues as shown in Figure 1.…”

Purpose The purpose of this study is to help the researchers, public, industries and government to realize the tremendous trends to improve the power quality of both sources and load side. Design/methodology/approach The work carried out in the Facts device and power quality issues. Findings Maintaining the quality of electric power is always a challenging task. The effect of power electronics devices leads to improper power quality. The use of FACTS devices is preferably the best approach to treat power-quality-related problems. Usually, all FACTS devices are constructed to operate on the side of either the source side or the load. Originality/value This paper explores a broad comprehensive study of various types of power quality problems and classification of FACTS devices with its recent developments. Furthermore unified power quality conditioner (UPQC) is particularly reviewed to highlight the advantages over other compensating devices. An exhaustive study of literature has been carried out and most significant concepts are presented

“…Obviously, it is deteriorated from the voltage/current power quality (PQ) imperfections, which includes voltage and/or current harmonic distortions, reactive power mitigation, power factor improvement, voltage-sag, voltage swell, un-balancing loading. These PQ issues in multi-feeder distribution systems are not a new things but the awareness of these PQ issues has been increased at current situation by end-user consumers [2].…”

Several artificial intelligent control schemes are highly used in several applications, in that ANFIS controller has been greatly recognized due to enhanced performance over the classical PI and Fuzzy controllers. At present the multi-feeder power distribution system is deteriorated with continuity of supply and poor power quality standards. In this multi-feeder distribution system, it is a regular consumer related issue which is acquired due to malfunctioning of massive non-linear loads. These loads create the voltage or current imperfections on distribution networks which disrupts the power quality of distribution system. An efficient and reliable active compensation scheme is used for attaining enhanced power quality features at PCC of multi-feeder distribution system with effective control functions. The Multi-Feeder Unified Power Quality Compensator (MF-UPQC) is optimal choice for attaining enhanced power quality features and it is a combined shunt or series compensator driven by common DC-link. This paper recommends the Adaptive Neuro-Fuzzy Intelligent Controller (ANFIS) based prediction technique for generation of optimal switching states to enhance performance of proposed MF-UPQC to compensate all voltage-current PQ imperfections. The performance of proposed MF-UPQC is verified by classical PI, Fuzzy and proposed ANFIS control functions by using MATLAB/SIMULINK tool and results are conferred with proper comparisons.
