Active wake control : An approach to optimize the lifetime operation of wind farms
article
The wind turbines within a wind farm impact each other's power production and loads through their wakes. Wake control strategies, aiming to reduce wake effects, receive increasing interest by both the research community and the industry. A number of recent simulation studies with high fidelity wake models indicate that wake mitigation control is a very promising concept for increasing the power production of a wind farm and/or reducing the fatigue loading on wind turbines' components. The purpose of this paper is to study the benefits of wake mitigation control in terms of lifetime power production and fatigue loading on several existing full-scale commercial wind farms with different scale, layouts, and turbine sizes. For modeling the wake interactions, Energy Research Centre of the Netherlands' FarmFlow software is used: a 3DparabolizedNavier-Stokes code, including ak-E turbulence model. In addition, an optimization approach is proposed that maximizes the lifetimepowerproduction, thereby incorporating the fatigue loads into the optimization criterion in terms of a lifetime extension factor.
