“…As a result, fault current levels are different in the grid-connected and islanded modes. Because of this difference, using fixed settings for micro-grid relays is not suggested and leads to relay maloperation and reduced network reliability [15].…”

“…Since the fault current is limited in an islanded MG with inverter-interfaced DGs, the overcurrent relays cannot operate correctly because they operate based on the fault current magnitude. Hence the use of the differential relays for microgrid protection is proposed for solving fault current limitation issues [15], [16]. However, not capable of distinguishing overload from fault current in the conventional differential protection, it will cause nuisance trip from overload current caused.…”

“…Another strategy is using inverter controller design as a protection system [15]. This method can be used only for the islanded mode, and having different short circuit level in the grid-connected mode is one of the main disadvantages of this method.…”

According to recent developments, the application of distributed generations (DGs) has become popular especially in distribution systems. The high utilization of distributed generating resources in modern power systems can cause new challenges from protection coordination perspectives. Changing the distribution system structure from single-supply radial system to multi-source ring network, leads to the bidirectional power flow and also has a vital impact on protection coordination issues. In addition, micro-grids can be operated under gridconnected as well as islanded mode, and fault current is extensively different for these two operation modes. Therefore, traditional protection algorithms cannot be used in the advancement of power systems. In recent years, several research studies have been conducted to investigate the improvement of protection schemes in micro-grids. This paper presents a comprehensive review on protection problems resulting from micro-grids embedded with DGs, and discusses some alternate protection strategies.

<p>A microgrid is required to provide reliable, quality and efficient supply of both electricity and heat demands to its customers when operates either in autonomous or in grid-connected modes. In this context, it is most important to address a comprehensive protection scheme of the microgrid suiting both the modes of operations. This paper concentrates on the impacts of various devices, like distributed energy resources (DERs), transformers, switches, microgrid topology, communication type, grounding type, to name a few, on the microgrid protection systems. The paper reviewes previous works for the various aspects, like characteristics, construction, of these devices in the light of protection. This review-work is useful for future research in the field of microgrid protection as well as in the selection of its devices.</p>
