Wind is one of the cleanest and cheapest renewable energies. One of the wind energy production technologies is use of small wind turbines installed in urban areas. However, installing these turbines in urban areas is associated with problems such as low wind speed and turbulence but if installed in the wrong location, their generated electricity is zero. In this study for the use of wind energy...
