A nonlinear control able to perform voltage and power stability in Direct Current (DC) MicroGrids for an efficient renewable energy integration that is capable of providing frequency support to an Alternate Current (AC) grid is introduced in this work. A generic DC MicroGrid modeling is developed, and the introduced controllers are shown to ensure grid stability, both by a theoretical analysis with a formal proof of stability using Lyapunov techniques, than by simulations performed in MATLAB. A comparison with classical Proportional Integral (PI) control techniques is described to show the performance improvements.
