Aerodynamics of wind turbine wakes Literature review
This report reviews the available literature on the aerodynamics of wind turbines and wind farms. Firstly, two introductory chapters are devoted to the physics of the flow around a wind turbine and the existing engineering models for blade and wake aerodynamics. The focus of this work is however on the numerical modeling of wakes. The difficulties in solving the Navier-Stokes equations are disc...
متن کاملReference wind farm selection for regional wind power prediction models
Short-term wind power forecasting is recognized today as a major requirement for a secure and economic integration of wind generation in power systems. This paper deals with the case of regional forecasting of wind power with a large number of wind farms involved. Due to the large amount of potentially available information and also because part of the wind farms may not be "observable", foreca...
متن کاملModeling and Simulation of Offshore Wind Farms for Farm Level Control
This paper presents a procedure for wind farm model simulation. The simulation model serves as a benchmark for controller development and verification in the EU-FP7 project Aeolus. A generic dynamic flow modeling relates single turbine production and fatigue load to the map of wind speeds. The model integrates the wind farm aerodynamics to the dynamics of individual turbines by means of wake me...
متن کاملSupplying Baseload Power and Reducing Transmission Requirements by Interconnecting Wind Farms
Wind is the world’s fastest growing electric energy source. Because it is intermittent, though, wind is not used to supply baseload electric power today. Interconnecting wind farms through the transmission grid is a simple and effective way of reducing deliverable wind power swings caused by wind intermittency. As more farms are interconnected in an array, wind speed correlation among sites dec...
متن کاملComprehensive Investigating on the Aerodynamic Influences of the Wheel Contact Patch
Computational fluid dynamics is implemented to investigate the influence of the wheel contact patch on the global car aerodynamics. Two main aspects of the problem are the contact step and patch shape. Three important parameters: step height, cut angle, and tire tread shape are taken into consideration. For validations of the numerical results, the experimental data are also considered. The obt...
