Illustration shows the concept of collective wind farm flow control. Existing utility-scale wind turbines are operated to maximize only their own individual power production, generating turbulent wakes (shown in purple) which reduce the power production of downwind turbines. The new collective wind farm control system deflects wind turbine wakes to reduce this effect (shown in orange). This system increased power production in a three-turbine array in India by 32 percent. Image: Victor Leshyk
