Initial costs of construction of micro-grids are the biggest hindrance in mass deployment of these solutions in rural areas (Ayodele and Ogunjuyigbe, 2015, Zebra et al., 2021).
Balancing the costs of development for micro-grid in rural areas will have to take into consideration the load that will be connected. Currently, the market is flooded with AC-based appliances and therefore, makes it necessary that AC micro-grid be preferred.
The paper highlights four critical aspects of microgrid design: 1) the challenges faced by rural communities and energy service companies, 2) microgrid subsystems and their associated technical developments, 3) system sizing and demand forecasting, and 4) practitioner-focused recommendations and best-practices.
Hence, the utilisation of micro-grids in rural areas. This paper investigated the recent developments in the utilisation of micro-grids in rural electrification. Challenges relating to financing and regulation are predominantly hindering the development of the projects. Nevertheless, some efforts have been made to design and develop these projects.
