摘要：AbstractThis paper addresses the problem of Current Sharing (CS) and Average Voltage Regulation (AVR) in Direct Current (DC) microgrids composed of several interconnected Distributed Generation Units (DGUs), power lines and loads. To achieve the control objectives (CS and AVR), the system is augmented with distributed integral actions. The existence of equilibrium points for the augmented system is proved and a distributed-based static state feedback control architecture is proposed. This latter guarantees the global exponential convergence of the system state to the set of all equilibrium points for which the control objectives are achieved, thanks to the passivity property of the DGU with local controller. Simulation results are provided to illustrate the effectiveness of the proposed methodology.
