UNIFIED DUAL ENERGY REGULATOR FOR MENDS SAGS AND SWELLS IN SUPPLY SIDE

A DVR can make amends for current sag/swell and distortion within the supply side current so that the current across a sensitive/critical load terminal is perfectly controlled. A unified power-quality conditioner (UPQC) is capable of doing the functions of both DSTATCOM and DVR. This paper presents a better controller for that dual topology from the unified power quality conditioner (iUPQC) extending its applicability in power-quality compensation, plus microgrid applications. Quite simply, the iUPQC will act as a static synchronous compensator (STATCOM) in the grid side, while supplying even the conventional UPQC compensations in the load or microgrid 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
