Power Quality Controller in Microgrid

This book deals with an improved controller for the dual topology of the unified power quality conditioner (iUPQC) extending its applicability in power-quality compensation as well as in microgrid applications. By using this controller beyond the conventional UPQC power quality features including voltage sag/swell compensation the iUPQC will also provide reactive power support to regulate not only the load-bus voltage but also the voltage at the grid-side bus. In other words the iUPQC will work as a static synchronous compensator (STATCOM) at the grid side while providing also the conventional UPQC compensations at the load or microgrid side.
