A NEW POWER COMPENSATION TECHNIQUE FOR GRID APPLICATION WITH REACTIVE POWER MANAGEMENT

Abstract

The ability circuit of the UPQC includes a mixture of a shunt active filter along with a series active filter connected inside a back-to- back configuration. The twin topology from the UPQC, i.e., the iUPQC, was presented, in which the shunt active filter behaves being an ac-current source and also the series one being an ac-current source, both in the fundamental frequency. This paper presents an enhanced controller for that dual topology from the unified power quality conditioner (iUPQC) stretching its usefulness in power-quality compensation, plus micro grid programs. Quite simply, the iUPQC will act as a static synchronous compensator (STATCOM) in the grid side, while supplying even the conventional UPQC settlements in the load or micro grid side. Experimental answers are presented to verify the brand new functionality from the equipment. Applying this controller, past the conventional UPQC power quality features, including current sag/swell compensation, the iUPQC may also provide reactive power support to manage not just the burden-bus current but the current in the grid-side bus.
