During the last years, distribution power systems working with Direct Current (DC) are gaining visibility and becoming more competitive. The growth in the number of theoretical and experimental studies using low-voltage DC grids can be justified as the result of three facts: the improvements in power electronics, the increase in the use of DC-based loads and a growing presence of DC energy generation among Renewable Energy Sources. However, there are still some major challenges limiting the deployment of DC in low-voltage distribution grids. Some of the subjects that need further studies and are also crucial for the standardization of DC in low-voltage environments, it is possible to highlight the choice of the distribution voltage levels, the design of selective protection schemes and the evaluation of power quality aspects. The objective of this paper is to analyze these main obstacles through a literature review with a focus on the worldwide tendencies and possible solutions.< Leer menos
