Abstract

The electrification of the rural areas of the planet has become one of the greatest challenges for sustainability. In fact, it would be the key to guaranteeing development for the poorest areas of the planet from which most of the raw material for the food market derives. The paradigm of centralized production is not applicable in these territories, because the distribution network would involve unjustifiable costs. For this reason, many studies have been carried out to ensure that the energy supply (specifically electricity) for off-grid utilities is maintained, in order to guarantee energy autonomy while reducing dependence on specialist assistance for the management of the system. In this work, a hybrid system (HRES) is proposed that combines the exploitation of solar radiation, wind power, and biomass using static devices, in order to improve the system’s availability and limit the cost of operation and maintenance. The aim of the study is to define promising lines of research, which can improve the sustainability of renewable harvesting systems to supply off-grids users.
