Abstract

Abstract: In this paper we study a distributed control scheme, achieving current sharing and average voltage regulation in Direct Current (DC) microgrids. The considered DC microgrid is composed of several Distributed Generation Units (DGUs) interconnected, through resistive-inductive power lines, with loads. Each DGU includes a generic energy source that supplies the loads through a DC-DC buck converter. Remarkably, the proposed control scheme achieves average voltage regulation without the need of voltage measurements. An experimental validation is performed to assess the capabilities of the solution in a real network. The initial results are promising and show an additional need to compensate for partly unknown resistances present at the DGUs.
