Implementation and analyses of yaw based coordinated control of wind farms.

Ahmad, Tanvir and Basit, Abdul and Ahsan, Muneeb and Coupiac, Olivier and Girard, Nicolas and Kazemtabrizi, Behzad and Matthews, Peter (2019) 'Implementation and analyses of yaw based coordinated control of wind farms.', Energies, 12 (7). p. 1266.


This paper presents, with a live field experiment, the potential of increasing wind farm power generation by optimally yawing upstream wind turbine for reducing wake effects as a part of the SmartEOLE project. Two 2MW turbines from the Le Sole de Moulin Vieux (SMV) wind farm are used for this purpose. The upstream turbine (SMV6) is operated with a yaw offset (α) in a range of −12◦ to 8◦ for analysing the impact on the downstream turbine (SMV5). Simulations are performed with intelligent control strategies for estimating optimum α settings. Simulations show that optimal α can increase net production of the two turbines by more than 5%. The impact of α on SMV6 is quantified using the data obtained during the experiment. A comparison of the data obtained during theexperimentiscarriedoutwithdataobtainedduringnormaloperationsinsimilarwindconditions. This comparison show that an optimum or near-optimum α increases net production by more than 5% in wake affected wind conditions, which is in confirmation with the simulated results.
