The impact of measuring a power curve inside a wind turbine array is investigated using computational fluid dynamics. The array consists of five aligned rotors that yaw with the free-stream wind direction. The flow-field in front of a wind turbine array changes with wind direction and hence the individual power output of each turbine. By incorporating the current IEC standards on power performance measurements, the bias in the power performance of turbines in an array over an isolated rotor is determined. The power changedepends on the position of the turbine in the array and reaches maximally 9.03% and minimally -0.84%

As outlined in detail in [2] the flow accelerates along the row of turbines, resulting in rotor 5 producing more power than rotor 1. In fact the power drops for rotor 1, as it is experiencing larger deceleration upstream than an isolated turbine. However, the changing velocities also affect the reference velocities, making the loss in power produced by rotor 1 appear smaller as function of wind speed. Turbine 5 seems to produce even more power as its power curve is shifted to the left.Isolated Turbine Turbine 5Turbine 1This work was performed inside the UniTTe project (unitte.dk), which is financed by The Innovation Fund Denmark, grant number 1305-00024B.
