Remote Islanded Microgrid: A feasible and economical solution for providing resilience and reliability to power systems in rural areas

The growing penetration of distributed energy resources has accelerated the development of microgrids, which are localized power systems capable of operating in grid-connected and islanded modes. In rural areas, where power systems face multiple challenges such as volatile markets and extreme events, remote islanded microgrids offer a resilient and sustainable solution to meet energy demands. This article provides a comprehensive overview of remote islanded microgrids, addressing the major considerations of their design and control. Two practical engineering projects in rural Iowa are presented as case studies, which further demonstrate the operational feasibility, economic benefits, and scalability of remote microgrids. The future challenges and research directions are also concluded in this article, presenting the great potential of remote islanded microgrids in enhancing the reliability, efficiency, and sustainability of power systems in rural regions.
