# Time-domain dynamic simulation of a wind turbine including yaw motion for power prediction. A new wind turbine simulation tool for a time-domain dynamic simulation was developed in this study. For the wind turbine model, the NREL 5MW reference wind turbine was used. Using measured data, the developed tool was applied to predict annual energy production from the wind turbine at four different sites in a complex terrain of Korea. The results were compared with those predicted by a commercial frequency-domain program widely used to predict the annual energy production from a wind turbine. Without a yaw control, the predictions from the proposed tool were close to those from the commercial wind farm design program. The results of this study suggest that the power production from a wind turbine can be predicted by the proposed time-domain wind turbine simulation tool with a proper yaw algorithm which is not available in commercial frequency-domain programs.

The Diagnostics of Power Boilers in Terms of Their Sustainability. A Novel Semi-Spar Floating Wind Turbine Platform Applied for Intermediate Water Depth. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. The current review focuses on studies concerning the numerical simulations of offshore wind turbine dynamics, including the modelling of the aerodynamic and hydrodynamic conditions of the environment and the reduced-order modelling of the wind turbine dynamic responses. In detail, the functions and mechanisms of each module in the numerical simulation of the wind turbine dynamics are articulated, which in turn demonstrates its importance for the design of offshore wind turbines, and hence the development of the offshore wind industry. Based on this review, it is argued that the vertical variations in wind velocities, the blade element momentum theory, the wave dynamic models, and the reduced-order model for structural dynamics are the major concerns for the numerical simulation of wind turbines.

# Time domain analysis for floating offshore wind substructure design. The expansion of the offshore wind industry to deeper water depths requires the usage of floating wind support structures, bringing new challenges to the industry. * Time Domain Direct Load Generation method: This is the most general method where hydrodynamic pressure and Morison loads are generated directly in the time domain before they are mapped to a structural Finite Element model. * Time Domain Load Reconstruction method: This method is an evolution of the Direct Load Generation method and can be used to drastically reduce the computational cost associated with hydrodynamic load generation. This method is the fastest and may reduce the simulation time from hours for direct simulation to just a few minutes. Frequency domain analysis for floating offshore wind substructure design. Webinar: New fast time domain simulation methods for floating wind substructure design.
