Power Quality Improvement Using DSTATCOM: A Review

Power electronic devices are an essential component of the majority of today’s commercial and domestic applications. Despite this, the power quality of these devices is quite poor for a variety of reasons, some of which include voltage fluctuations and flicker, harmonics, transients, voltage imbalance, and many more. Voltage fluctuations like this cause the greatest number of problems in electrical distribution networks. In this review article, a variety of strategies, such as network reconfiguration and devices of the compensatory type, are reviewed in order to improve the power quality in the distribution systems. There are several power quality challenges that have been portrayed along with their features. Filters, unified power quality conditioners (UPQC), dynamic voltage restorers (DVR), and distribution static synchronous compensators (D-STATCOM) are only some of the methods that have been considered for improving the power quality in distribution systems. Additionally covered are the design parameters, as well as the application of these strategies in electrical machines..
