“…The BEM theory using the blade element momentum is applied to calculate the speed and load acting on the wind turbine rotors according to the wind speed, rotor rotation speed, and pitch angle (Agarwal and Manuel, 2008). The generalized dynamic wake (GDW) was developed for the aerodynamic analysis of high-speed blades such as helicopters (Peters et al, 1989;Suzuki, 2000;Kim et al, 2019). In this study, the results were derived by applying wind speeds below the rated speed to accurately identify the response characteristics of a wind turbine by the wind.…”

“…Song and Yoo (2017) carried out dynamic response analysis according to the shapes (monopile, jacket, and dolphin) of substructures for a 2.5 MW offshore wind turbine and found that the wave load acting on the jacket-type substructure had the smallest value. Kim et al (2019) examined a technique for predicting the wake of a wind turbine to remedy the weaknesses of the aerodynamic analysis model of the Fatigue, Aerodynamics, Structures and Turbulence (FAST) program (Jonkman, 2007) developed in the National Renewable Energy Laboratory (NREL) and conducted a study on the optimization of wind turbine arrangements. Tran et al (2021) conducted a study on the bending performance of a substructure when sea winds, waves, and ocean currents act on a 3 MW jacket-type offshore wind turbine as environmental external forces.…”

Owing to the increasing global environmental regulations and energy crisis, wind energy is gaining global interest as eco-friendly alternative renewable energy that can be sustained. The wind power generation technology that converts fluid kinetic energy into electric energy has already been technologically verified, and large land-based wind turbines have been constructed worldwide since the 1980s (Jang and Sohn, 2011).However, constructing large land-based wind turbines causes various issues such as spatial limitations, noise, radio interference, and visual discomfort. Moreover, high energy generation efficiency is difficult to obtain in land-based wind power generation owing to low wind speed and turbulence caused by interference from surrounding terrain features (Li et al., 2018). Offshore wind power generation results in high power generation efficiency because the offshore wind speed is, on average, at least 70% higher than that on land, and large wind turbines can be installed because wide installation spaces are available (Park et al., 2021).Consequently, offshore wind turbines have recently been installedand operated in numerous regions, and many fixed type wind turbines have been installed in relatively shallow coastal areas. Particularly, in South Korea, the Jeju Tamla Offshore Wind Farm was constructed in 2017 and has ten 3 MW wind turbines in operation, and the Offshore Wind Farm in the Southwestern Coast of Yellow Sea was constructed in 2019 and has twenty 3 MW wind turbines in operation (Jeong et al., 2020; Oh et al., 2020). As the demand for offshore wind turbines increases, studies on them have been actively conducted. Shi et al. (2011) carried out dynamic response analysis according to the shapes of the substructures of a 5 MW offshore wind turbine and reported that the load and dynamic response acting on a monopile-shaped substructure have larger values
