This article seeks to show how the use of direct current can be advantageous. Based on recent literature, provides an overview of the advantages and challenges to be overcome. Showing that today, new technologies and new conditions favor the adoption of the direct current system. However, the idea is not to replace all the existing AC system to DC, but a hybrid system available to the consumer. The review points out that there are many challenges to be overcome so that the DC power can be exploited to full potential. The main challenges are regulation and standardization and development of protections, requiring more studies to find appropriate solutions.
