A novel hybrid control strategy of wind turbine wakes in tandem configuration to improve power production

• A novel hybrid wake control strategy to improve power production of wind farms is presented. Changing both yaw and tilt angles the upstream turbine can provide largest deflection. Total generation improvement two tandem turbines by 6.1%. Annual energy enhancement 3.7% achieved at θ = 30 o ϕ 24 . The that operate in region produce less may suffer serious structural issues due highly unsteady flows, which reduce life expectancy turbines. In this study, a for farm proposed, based on accurate large eddy simulations coupled with actuator line method. combined effects angle methods performance downstream layouts have not yet been investigated. This work would be first attempt evaluate wake-control It found vortex stronger lower because more parts rotor are affected wakes turbine. An optimisation analysis also provided find optimum deflection maximize electrical generation. results show an accumulative increment 17.1% controlling ( ) , φ obtained present study approximately 6.1% higher than previous techniques. By using strategy, annual achieved, wake-controlled layouts.
