Technological and dimensional improvements in onshore commercial large-scale wind turbines in the world and Turkey

Wind turbine technology has advanced significantly during the past 10 years all around the world. To raise the turbine capacity factor, developers are building bigger, more dependable wind turbines with bigger hub heights and rotor diameters. Long-bladed, large-rotor, tall-tower, and low-specific power wind turbines with higher capacity factors (CFs) developed in this direction may become more important in the future energy systems since they can generate electricity in more economical conditions. The increase in nameplate capacity, hub height, and rotor diameter of onshore wind turbines around the world as well as in Turkey is, therefore, examined in this study. The impacts of this development in wind turbine size on the levelized cost of electricity, total installed cost, and CF are analyzed. Moreover, the effects of this expansion on turbine-specific power capacity, wind farm capacity, and the number of wind turbines per GW are thoroughly evaluated. To promote future advancements in large-scale wind turbine technology, these inspection results can be used to evaluate the technical and financial viability of turbines. They can also serve as a useful data source and a substantial advantage in the construction and development of new wind energy facilities.
