Perspectives for DC distribution adoption in Brazil

The main purpose of this paper is to discuss possible means for DC distribution adoption in Brazil in medium term, basing the discussion on the perspective of an emerging country. A main path to be explored is the progressive adaptation of PV residential and commercial distributed generation systems into a DC microgrid, allowing energy efficiency, power quality and energy management improvements. A DC microgrid testbed in current development in the Federal University of Minas Gerais (UFMG) will also be described and simulated results will be used to demonstrate the behavior of the proposed architecture.
