Analysis of Cost Estimation and Wind Energy Evaluation Using Wind Energy Conversion Systems(WECS)for Electricity Generation in Six Selected High Altitude Locations in Nigeria

摘要

Two commercial wind turbines namely AN Bonus 300 kW/33 and AN Bonus 1 MW/54 were technicallyudassessed for electricity generation in six selected high altitude sites spreading across the udNorth-West and North-East geopolitical regions of Nigeria by computing their capacity factors, udannual power and energy outputs. The economic evaluation of using the two wind energy conversion udsystems (medium and large) for electric power generation in the selected locations were also udestimated using the present value cost method. The results showed that capacity factors of the udtwo turbines in the selected sites ranged between 4.6 and 43%. Average minimum cost per kW h was udobtained in Kano as $0.0222/kW h with AN Bonus 1 MW while the highest average cost is ud$0.2074/kW h with AN Bonus 300 kW in Kaduna. The highest cost in each of the location was udobtained with the medium WECs (AN Bonusud300 kW). In addition, Kano and Katsina were also found to be very economical for any of the udadopted wind turbine models. Gusau and Kaduna, at cost of unit energy of about $0.30/kW h were udfound to be more profitable for non-connected electrical and mechanical applications (water udpumping, batteryudcharging) than diesel generator.ud
