Analysis of wake effect on the annual energy production of wind farms

This paper analyzes the impact of aerodynamic wake phenomenon caused by wind turbines on the power generation of other turbines inside the same wind farm, which can significantly affect the energy production of the farm. The relevance of the work is associated with the great expansion of the wind po...

Analysis of wake effect on the annual energy production of wind farms
description This paper analyzes the impact of aerodynamic wake phenomenon caused by wind turbines on the power generation of other turbines inside the same wind farm, which can significantly affect the energy production of the farm. The relevance of the work is associated with the great expansion of the wind power industry which has been experienced in the last years around the world and particularly in Brazil. Therefore, the objective of this work is to evaluate the Annual Energy Production (AEP) of different wind farm layouts affected by wake effect. In addition, the variation in wind speed in a given location throughout the year should also be considered by using an annual series of wind speed data. With this purpose, the adopted methodology is a mathematical modeling by Jensen multiple wake model with adaptation of a MATLAB computational algorithm to calculate the Annual Energy Production and the layout efficiency of wind farms with unidirectional wind. The results obtained by the algorithm were consistent with values reported in literature for unidirectional wind and multidirectional wind with constant wind speed, thus validating the values calculated by the algorithm. In the case of multidirectional wind with variable wind speed, the difference between the results was significant, thus proving how important is the use of the proper wind speed data. Furthermore, it was verified that more efficient wind farm layouts can have an AEP similar to that from less efficient layouts with fewer installed turbines, thus reducing the required investment.
