A Model for Evaluating the Basic Wake Effect in the Calculation of Wind Turbine Power Output on Offshore Wind Power Plant

One of the most important topics of offshore Wind Power Plant (WPP) installation is the wake effect of the wind turbines on each other. This situation reduces annual energy production of WPP. WPP installation should be performed by considering the loss of production due to the wake effect. Nowadays, many methods are used for calculation of wake effect. Among these methods, the Jensen method is mostly preferred due to the simple and high degree of accuracy. In this study, Wake effect between two wind turbines is modeled by using Jensen method for variable wind velocities and frequencies at the same elevation in a region. The model is formed in the Matrix Laboratory (MATLAB) software development environment. Also, Wind Atlas Analysis and Application Program (WAsP) software is used to verify the former model. In this software, two wind turbines are placed in offshore region. In this case, gross and net production values of turbines were calculated. When the results of MATLAB and commercially used WAsP model results were compared, the approximately same production values were obtained. These results show that the developed model can be used in calculations in offshore WPP
