Abstract
The purpose of this study is to evaluate the wind potential of Arak, located in the middle of Iran and to perform technical and economic assessment of utilizing an appropriate micro wind turbine based on the wind characteristics of the region. To achieve this aim, 10 years wind data in Arak was analyzed to determine wind energy potential using Weibull distribution function. It became clear that Weibull distribution was adequate for this study. Average of shape factor and scale factor are 4.31 and 5.19 respectively. The range of mean yearly wind speeds is obtained as 3.7 to 5.61 m/s at 10 m height. According to the characteristics of the understudied site, two wind turbines, SKYSTREAM3.7 and WHISPER500 were selected for power generation and then economic analysis was carried out. The results indicate that, WHISPER500 generates annual energy of 3975 kWh and internal rate of return for this turbine is 20.9% while these values for SKYSTREAM3.7 are 2961 kWh and 20.9%, respectively. According to the calculations, currently the wind power generation is not economically justified for Arak due to low returns of capital costs, but more supports from the government like devoting loans and considering the carbon credits can make the wind energy projects in Arak more viable.
