An Integration of dual UPQC controller for power quality compensation by extending its voltage regulation at grid side as a STATCOM

Abstract

This paper presents a modified controller by integrating dual unified power quality conditioners: iUPQC controller with its utilization in microgrid and power-quality utilizations. By applying this regulatory controller it extends the quality of power characteristics just like the UPQC controller it offers reactive power regulation both at load-side bus voltage and at grid-side bus voltage, which also compensates voltage swell & sag. At grid-side iUPQC controller will work as a STATCOM, by providing all the conventional UPQC applications both at the grid-side and load-side. Simulink consequences are providing to validate the latest predictability of the apparatus.
