Abstract: This article presents an up-to-date systematic review of the status, progress, and upcoming advancement regarding DC-microgrid. In recent years, the attention of researchers towards DC-microgrid has been increased as a better and viable solution in meeting the local loads at consumers' point while supplementing to stability, reliability, and controllability of a given power system. The topology, configuration, protection challenges, and issues with DC- microgrid are very much different compared to those of AC-microgrid. Moreover, the grounding requirement and its configuration are also playing an important role in DC-microgrid compared to AC-microgrid. Therefore, a separate study on DC-microgrid with a 3600 angles of view is necessary. In this regard, this paper has tried to accumulate all recent advancements on the DC-microgrid domain in addition to traditional deeds. By this process, the authors have adopted a review strategy comprised of few specific tasks, for example (i) preparation of article database related to microgrid protection; (ii) designing inclusion/exclusion criteria to filter out the required and important articles (iii) analysing each articles based on critical viewpoints. In general, this article presents an extensive survey and analysis of methods proposed by different researchers dealing with DC microgrid protection and grounding issues. At the end, this article has also suggested a few recommendations and questions regarding future studies. We hope that the outcomes of this review paper will definitely help the readers working on a similar domain and found to be an encouraging research field.
