Validation of a Three-Dimensional Dynamic Wind Farm Flow Model for Real-Time Simulation

This paper presents simulation results of a real-time capable three-dimensional wind farm flow model, which provides an environment to simulate aerodynamic conditions in wind farms and turbine interactions. It allows to develop, validate and improve individual turbine control, collective wind farm flow control and wind farm cluster optimization techniques while taking grid interactions into account. Wind farm optimization and grid integration will gain more interest, as wind energy is expected to strongly increase in the next years, resulting in more wind farms which are clustered and closely located. This work specifically addresses dynamic wake modeling to predict the impact of wind turbines on wind farm flow and power generation of individual turbines within a wind farm through wake interactions. The simulation framework is briefly described and particular modifications of the implemented wake model are presented. Simulation results are shown to demonstrate the model capabilities and are validated against data from literature to asses its accuracy and to determine further possible improvements.
