Microgrids with a potential structure developed as a system that combines renewable energy sources, energy storage systems and loads. Microgrids are capable of improving the quality, Reliability and efficiency of the power delivered to the consumers both in grid connected and Islanded mode. However, when implementing microgrids, a variety of problems concerning the security issues have to be handled. The existing modes of operation and the existing DERs are capable of causing the traditional security schemes to be unproductive. Therefore, novel security approaches have been developed. Thus, in this paper a complete review on the modern security approaches is discussed considering the security issues explained above. Prominence to surveys related to adaptive protection is exhibited in this paper, which are believed as favourable solution for microgrid safety and control. The paper briefly presents a microgrid structure and addresses the safety and control challenges observed in the existing Microgrid. Later the paper focuses on overview of Adaptive protection and the possible novel protection schemes for microgrid safety and control found in the technical research articles. However, it can be noticed that efforts are still required to attain a complete solution for the safety and control challenges observed in the existing Microgrid.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
