In this document a brief review of the DC microgrids generalities with emphasis in the control architecture is done. A novel hybrid-control architecture to take care of the inner, primary and secondary levels of DC microgrids monitoring, is simulated under different conditions. In the inner control architecture an Modified Exact Feedback Linearization with integral action approach, is proposed for control current or voltage in a Buck converter, designed to be part of the DC microgrid.
The controllers are tested in simulation using Matlab-Simulink . Results are compared with classic PID controllers and evaluated under two different mathematical
tools (Mean Square Error, Integral Time Absolute Error) in order to prove their effectiveness. The evaluated data show that the proposed approach outperform the
classical methods..
