Energy Optimization of a Purely Renewable Autonomous Micro-Grid to Supply a Tourist Region

An autonomous micro-grid is generally based on fossil fuels. Recently, these systems are favored integrating existing renewable energies in very specific areas to achieve the sustainability of the energy sectors. Hydrogen is considered as means of storing and transmitting energy, especially nowadays, and the sufficiency required by remote areas can be achieved by using hybrid techniques. Our search is the electrification of a tourist site in the region of Kenadsa. In Bechar city, which is located in the south west of the Algerian state. Using an independent small electric network based on the hybridization of renewable energies. The hybrid energy system must be provided with a cost-effective energy solution for the project by optimizing its components, controlling, sizing them with better selection. This research evaluates the technical and economic feasibility of renewable energy systems. This work aims to reduce the total net cost of the pre-determined system as well as the cost of energy and unfulfilled load and to make CO2 emissions lower, this kind of studies is carried out using the simulation program HOMER Pro. At the end we ca say that the proposed system has good results for electrifying remote areas and at a conservative cost of electrical energy in order to establish sustainable areas.
