Results of the laboratory tests of a novel regulator for meshed low-voltage networks

Abstract

This paper presents the results of the laboratory test of a novel voltage and current regulator for meshed operated low-voltage grids. The regulator can adjust the mentioned values by adding a complex control voltage to the grid voltage. Besides the analytical basics, a method based on characteristic curves is explained which can be applied to heavily meshed grids. The regulator has been tested in extensive laboratory tests. In the laboratory, which consists of a grid model, loads and PV-inverters, tests with realistic voltage and currents have been performed. The results are presented in this paper.
