OPTIMAL PLACEMENT OF HORIZONTAL - AND VERTICAL - AXIS WIND TURBINES IN A WIND FARM FOR MAXIMUM POWER GENERATION USING A GENETIC ALGORITHM
A simple wake model following the work of Jensen [4] is developed for the VAWT. We have also developed a more complex wake model for VAWT using the double stream-tube model of Paraschivoiu International Journal of Energy and Environment (IJEE), Volume 3, Issue 6, 2012, pp.927-938 ISSN 2076-2895 (Pri[r]
