“…The physical and cyber risk factors are then calculated in subsections A and B. Since a microgrid is inherently a cyber-physical system [47] [48], it is important to integrate the risk assessments of these two layers to holistically evaluate microgrid resilience. The combined risk assessment results provide an effective way to prioritize which mitigation measures will have maximum impact on increasing the resilience of the microgrid.…”

Microgrids are being increasing deployed to improve the operational flexibility, resilience, coordinated-energy management capabilities, self-adequacy, and increased reliability of power systems. This strong market growth is also driven by advances in power electronics, improved control systems, and the rapidly falling price and increased adoption of distributed energy generation technologies, like solar photovoltaics and storage. In the event of grid outages, microgrids can provide a backup source of power; providing resilience to the critical loads; however, this requires that the microgrid itself is resilient to physical and cyber threats. Building highly resilient microgrids requires a methodological assessment of potential threats, identification of vulnerabilities, and design of mitigation strategies. This paper provides a comprehensive review of threats, vulnerabilities, and mitigation strategies and develops a definition for microgrid resilience. The paper also develops a methodology for designing resilient microgrids by considering how microgrid designers and site owners evaluate threats, vulnerabilities, and consequences and choose the microgrid features required to address these threats under different situations.

“… Designing feeders for microgrid: As per the existing the power system, feeders till date are designed based on the strong sources of power generation and distribution. However, a challenge arises when the availability of feeders according to the microgrids demand remains unfulfilled 37‐39 Identifying the microgrid's modes of operation: Each integrated power source vs load scenario in the microgrid should be identified and detailed for instances like temporary switchover or emergency shedding.…”

Summary A microgrid is a trending small‐scale power system comprising of distributed power generation, power storage, and load. This article presents a brief overview of the microgrid and its operating characteristics. The integration of microgrids with the existing power system has been challenging and requires time to time modifications. To analyze the changing demand, the article discusses the modifications made in IEEE 1547 integration standards. The article recollects and reviews the control strategies of certain microgrid testbeds installed all around the world. A focus has been drawn toward the integration of microgrids in a developing country like India. An overview of the policies followed and the challenges faced to integrate the microgrid in the Indian power industry is presented. The article concludes with the worthy findings for the future aspects of research to improve the overall performance along with the smooth integration of the microgrid.

“…To avail of autonomous grid operation, the SMG can be operated in a grid‐connected or islanded mode of operation. During the grid disturbance condition, the SMG detaches the interlinked MG from the grid and make the system islanded and fed only to the local load, not to the utility grid 5,6 . In both autonomous modes of operations, the power quality (PQ) and power reliability (PR) issues are considered as a major challenge during real‐time applications.…”
