Optimization of Nanogrids for Remote Off-Grid Communities

Abstract

This review article delves into the advancements in the realm of nanogrids and their potential in addressing energy challenges, particularly in regions with limited access to centralized power grids. The paper reviews the work in the areas of nanogrids as solutions for regions like sub-Saharan Africa, where a significant population lacks access to main grid electricity. The integration of multiple nanogrids within a community, coupled with an investor energy bank, is explored as a means to alleviate the economic burden of energy storage and to harness the full potential of solar energy. The article also examines the challenges faced by centralized power grids and the shift towards distributed generation (DG) as a remedy. The concept of nanogrids is further elaborated, discussing their control topologies, techniques, and the potential of interconnecting multiple nanogrids to form a microgrid. Lastly, the co-design of solar generationbased nano-grids and water treatment in remote areas is studied, emphasizing the importance of providing essential drinking water and electricity to underdeveloped regions. The integration of solar-powered electricity with water treatment processes offers a unique solution to address both electricity and water needs in such areas.
