“…The SOP is a grid-connected converter and the main purpose is to improve the power quality of the DNs. An IEEE Guide for the application of PEs for power quality improvement of DNs [36] and reference [37] mention the responsibilities of PEs converter like dynamic voltage restorer, static voltage regulator, static transfer switch and distribution STATCOM. Standards like IEEE1547-2018 [38], [36] and operations perform by SOP mentioned in literatures are considered to define the operation standard of SOP in DNs, are given in Table 3.…”

The main objective of this paper is to present a comprehensive review of soft open point (SOP), an emerging power electronics technology to maximize future distribution networks' (DNs) resiliency and flexibility as well as increase hosting capacity for distributed energy resources like photovoltaics and electric vehicles. The SOP is currently an active area of research and ongoing development of new control techniques for SOP and optimization algorithm for the optimal use of SOP in DNs produces new techniques until DN operators use it comprehensively in their systems. The motivation for this work is to present the research that has been completed for the SOP and summarize the duties of SOP in DNs according to the literature and propose advanced duties for SOP according to modern standards. Finally, future research directions are mentioned to pave the way for research in the coming years to drive the DNs towards more flexibility and 'Robust' from controllability, stability, and protection structure point of view. INDEX TERMS Distribution networks, grid-connected converters, power electronics, soft open point, normally open points.

Power quality is one area which concerns the electrical professionals today. Advances in power electronics usage in variable frequency drives, distributed generations and uninterrupted power supply destroy the quality of power in distribution system. Harmonics especially destroys the shape of the source current and reduces the distribution equipment's capacity. This paper presents a performance comparison of both Fuzzy-logic controller and PI controller based FACTS devices for power quality enhancement in power-distribution network. Five-Level DSTATCOM is employed for PQ enhancement. LSCPWM pattern of pulses excites the DSTATCOM while reference signals are obtained from IRP based theory. PI and fuzzy controller performance (in the process of generating reference currents) in enhancing the power quality reducing the harmonic current distortion in distribution system is analysed in this paper.

In this paper, a PWM inverter is proposed for improvement of power quality i.e., reduction of total harmonic distortion (THD). The power quality problems reduce the lifetime and performance of equipments. The proposed system reduces the THD which is generated from the nonlinear loads. Because presence of harmonics leads to problems like overheating, failure of insulation etc. Here the simulation results of the proposed system is studied using MATLAB SIMULINK. Using the system, a lower THD is achieved which shows the effectiveness of the system.
