Line voltage regulator based on magneticcontrolled inductors for low-voltage grids

Abstract

The rapid expansion of distributed energy resources in the German low-voltage network has led to voltage violations, especially in rural areas with little electric load. To address this issue, this study presents an innovative line voltage regulator (LVR) for low-voltage networks which operates with a magnetic-controlled inductor. Therefore, a software environment for simulating magnetic-based regulators and a hardware test bench for LVRs are developed. Results of the simulations and the laboratory tests of the first prototype device are provided.
