A new concept to improve power production performance of wind turbines in a wind farm

A modern wind farm usually consists of multiple wind turbines arranged in an organized pattern or array. Wake interferences among wind turbines have been found to affect the performance of the wind turbines significantly. Researchers studied the effects of relative rotation direction of wind turbines on the wake interferences among tandem turbines for improved power production performance of wind turbines in a wind farm.
