This paper presents a comprehensive review of the available microgrid protection schemes which are based on traditional protection principles and emerging techniques such as machine learning, data-mining, wavelet transform, etc. . Device-level controls play a crucial role in how microgrids are controlled and protected. There is no guarantee that behavior of DERs will be common amongst device types or even amongst vendors. This complicates control philosophies and can lead to unintended and unmodelled instabilities in the. . How protection devices such as residual current circuit breakers, miniature and moulded case circuit brea-kers, and surge protective devices should be selected for an example microgrid is discussed while referring to the relevant standards. The design of both systems must consider the system topology, what generation and/or storage resources can be connected, and microgrid operational states (including grid-connected, islanded, and transitions between the two). In the next section, the protection of a grid connected. . The main protection challenges in the microgrid are the bi-directional power flow, protection blinding, sympathetic tripping, change in short-circuit level due to different modes of operation, and limited fault current contribution by converter-interfaced sources.
