Improvement of Power Quality Using PV with UPQC

Abstract

The ability of energy to reach consumer devices is determined by the quality of the power that was used to create it. Using a Unified Power Quality Conditioner (UPQC) to improve power quality on feeders in distribution system, this study offers a new joint that may be utilized in conjunction with the UPQC. The unified power quality conditioner makes use of active power filters, which are capable of altering both voltage and current at the same time. The UPQC connected to the feeders by means of a cable (Figure 1). (Lines). When it comes to resolving power quality concerns and reducing the number of transmission lines at a substation, the Unified Power Quality Conditioner is the most effective customized power equipment available on the market. An UPQC system with a three-phase bus that is fed by PV is modeled and tested. Sagging is caused by heavy loads, whereas swelling is caused by light loads. Solar arrays fed by UPQC are becoming increasingly popular as a means of reducing the severity of these power quality issues. MATLAB is used to analyze and report on the data that has been collected, This study makes use of concepts such as automatic power factor (APF), photovoltaic, proportional, and integral controllers (PI).
