Techno-economic assessment of wind energy conversion systems for power generation for the city of N'Djamena in Chad

Abstract

Around the world, with a significant increase in installed capacity each year, wind power is one of the most profitable forms of renewable energy. In this study, three commercial wind turbines, namely Bonus 300kW/33, Bonus 1MW/54 and Vestas 2MW/80, were selected as large-scale wind power conversion systems (WECS) for the technical evaluation of production electricity for the N'Djamena site in Chad. The economic evaluations of these three WECS for power generation are calculated using the Cost Calculation Technique (PVC). Thus, the results obtained show that the highest capacity factor is 15.29% with Bonus 1MW/54 while the lowest at 11.39% with Bonus 300kW/33. The minimum average cost per kWh is 23 US$ / kWh with the 1 MW/54 Bonus, while the highest cost is 33.8 US$ / kWh with a Bonus of 300 kW / 33.
