Evaluation of Electricity Excess in Hybrid Energy System

Objectives: In the present work, a technico-economic study of a hybrid system (wind-photovoltaic-diesel) with fully autonomous electric power supply was carried out using HOMER software in the Tindouf region of Algeria. Methods / Statistical Analysis: This study have made based on available climatic data, after studying and analyzing the various possible configurations, we have opted for an optimal configuration consisting of three types of generators: photovoltaic, wind, converter, with a storage system and Connected to the network. The use of a storage system makes it possible to better exploit the renewable potentials available by charging the batteries at times of high production by the wind or PV. Finding: The results showed that the integration of renewable energies in the hybrid system represents a rate of 97.3%, of which 82% in wind turbine, and 16% in photovoltaic; AC primary load is 39%, dirty grid is 61%, the power converter develops its maximum power with full batteries and satisfied and accomplished load. Application / Improvements: At the same time, an excess of electrical production is reached during the whole year; day and night, with a rate of 59.2%.
