Line Voltage Regulation in Low Voltage Grids

Abstract

Despite volatile distributed energy resources and numerous variable loads, low voltage microgrids are required to ensure the permitted voltage range through an optimized operation and coordinated control. In order to resolve voltage violations, this paper presents a research on a novel line voltage regulator for distribution grids and microgrids which is characterized by a high degree of robustness and minimum side effects on power quality. The paper deals with its setup and features as well as its performance and influence on power quality, which is demonstrated by laboratory tests.
