Abstract

In recent years, there has been an increasing interest in applying micro-grid systems not only to improve reliability but also to enhance power quality. One of the major challenges associated with the implementation of micro-grids is to design an appropriate protection scheme which has the ability to protect micro-grids in both grid-connected and islanded mode. In order to overcome this challenge, different approaches have recently appeared in the literatures. This paper aims to provide an introspective review of the available protection schemes used for addressing micro-grid protection issues in both grid-connected and islanded mode. In addition to description of existing protection schemes to date and categorizing them into specific clusters, a comparative analysis is done in which the merits and demerits of each methodology are evaluated.
