Energy and Economic Analyses of a New Ducted Small Wind Turbine

Growing energy demand and considering the importance of environmental issues in recent decades, the utilization of renewable energies is expanding accordingly. Among renewable energies, wind power and technology are growing and evolving more rapidly than other renewable energies. This research studied turbine is modified Wuxi Ruifeng 2KW 48V with two new ducts (Sii and Prototype). Wind data of four areas in Iran has been used to analyze energy production and cost in different wind patterns. Levelized Cost of Energy and Annual energy production for the wind turbine with and without ducts are evaluated in different areas. Results showed that ducts in high wind speeds have little effect on increasing annual energy production and reducing energy cost (ducts can even negatively impact). However, in areas with low wind speeds, they can increase annual energy production by up to 4 times and reduce energy costs by up to 2.5 times.
