Implementation and Analyses of Yaw Based Coordinated Control of Wind Farms

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 () in a range of -12degrees to 8 degrees for analysing the impact on the downstream turbine (SMV5). Simulations are performed with intelligent control strategies for estimating optimum settings. Simulations show that optimal can increase net production of the two turbines by more than 5%. The impact of on SMV6 is quantified using the data obtained during the experiment. A comparison of the data obtained during the experiment is carried out with data obtained during normal operations in similar wind conditions. This comparison show that an optimum or near-optimum increases net production by more than 5% in wake affected wind conditions, which is in confirmation with the simulated results.
