This paper reviews and discusses the use of adaptive protections in microgrids. The main goal of the paper is to review the progress made in the last 10 years, to identify the challenges that are still present, and to note the current trends in the use of these protections in microgrids. The analysis is based on applications implemented since 2007, and on a wide bibliographical review of books, theses, patents, scholarly papers, conferences, technical reports, and experts' experiences. The paper includes a comparative table that summarizes the reviewed literature and its findings. The paper is of interest to academics who do research on development and implementation of new robust and reliable protection schemes in microgrids, and to those in the industrial sector, who implement electric microgrids, and who want to understand the impact of their protection schemes.
