Abstract

Microgrid technologies are very effective in integrating the distributed energy resources for providing high quality and high reliability of electric power. The Microgrid is often deployed as a cable-based and small-scaled distribution network at a low voltage level. As a result, the line impedance is much more resistive. This paper presents a minimum output current tracking control method for interface converters of distributed energy resources to improve the power sharing issues in a low voltage Microgrid system. The proposed technique manipulates the droop control to achieve minimum converter output current under different conditions of loads and transmission line characteristics. The operation principles are discussed below. Simulation and laboratory test results are also presented to validate the proposed method.
