In this letter we propose a new 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. Each
DGU includes a generic energy source that supplies a local
current load through a DC-DC buck converter. The proposed
distributed control scheme achieves current sharing and average
voltage regulation, independently of the initial condition of the
controlled microgrid. Moreover, the proposed solution requires
only measurements of the generated currents, and is independent
of the microgrid parameters and the topology of the used
communication network, facilitating Plug-and-Play capabilities.
Global convergence to a desired steady state is proven and
simulations indicate a good performance.
