Analysis of non-linear adaptive voltage droop control method applied to a grid connected DC microgrid

Currently, the standards of reliability and power quality indicate a new design of the Electric Power Systems (EPS), in which the model of centralized generation gives way to the Distributed Generation (DG). One way to achieve the integration of sources in DG is using DC microgrids, since renewable energy sources can be integrated into systems using DC as well as energy storage and UPS, eliminating conversion stages. The voltage control in these systems is of paramount importance. Therefore, this paper proposes the use of a methodology for nonlinear control associated with the concept of voltage droop control in a grid-connected DC microgrid. Simulation results are presented and the behavior of the system is analyzed.
