Review on Design of Improved Unified Power Quality Conditioner for Power Quality Improvement

Abstract
Non-linear loads are frequently affected by power quality (PQ). Resonance mechanisms, condenser overheating, and other performance-degrading consequences are all caused by harmonic currents. Voltage sags are common in low-voltage systems. While harmonic currents are pumped into the grid, equipment like electrical converters improve the entire response of an equal load. The necessity for reactive power is well-known for lowering feeder voltage and increasing losses. Harmonic currents can cause a poor signal by distorting the waveform voltage. There's also a rise in the number of loads that need significant sinus tension to work correctly. People are getting more interested in power conditioning solutions as electronic devices become more power-sensitive. As a result, if the amount of electricity produced falls below a specified threshold, compensation must be supplied. The Unified Power Quality Controller (UPQC) is a type of AC transmission system that can manage voltage, impedance, and phase angle. UPQC (United Provinces and Territories (FACTS). A Dynamic Voltage Restorer, a Fuzzy Controlled Shunt Active Power Filter, and a UPQC are required to improve the power quality of the power system. DVRs (Dynamic Voltage Restorers) are power converters that are installed in responsive load arrays to protect against supply disruptions. Because of its short response time and high level of dependability, it is an excellent tool for increasing the quality of electrical power. The simulation results were compared to the basic system and enhanced to demonstrate the efficiency of the suggested system.
