Distributed-based Integral Action for Current Sharing and Average Voltage Regulation in DC Microgrids

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