Power Quality Improvement Using Pso Optimization Based Upqc Controller

Abstract

To address power quality issues, the unified power quality conditioner, one of the custom power devices in FACTS, is widely utilized in the distribution systems that are voltage- and current-related. The advantage of the recommended UPQC technology is that it can reduce the dc-link voltage without sacrificing its ability to compensate for it. This ground-breaking technique helps in giving the necessary voltage to the UPQC's series and shunt active filters. Through directly linking the system neutral to the distribution system and using it as a filter, such a type of architecture does away with a capacitor in series with the interface's inductor and crossing the active shunt filters are implemented to satisfy the need for the voltage source inverter's fourth leg. This article offers a compelling suggestion additionally.
