A common metric used to describe wind farm performance is the levelised cost of energy (LCOE), which is defined as the net present value of the cost to produce a unit of energy. The turbine power output, OPEX, and initial investment cost are all considered in the LCOE evaluation.
Wind turbine reliability data comprise the historical failures, repairs, and downtimes of a turbine and its subassemblies. A thorough understanding of WT reliability is critical to the development of effective operation and maintenance (O&M) strategies and to an improved WT and wind farm performance.
Moreover, offshore wind turbines can be larger than those on land, as it is more feasible to transport large turbine components by sea. Finally, the lower wind shear and turbulence in offshore installed wind farms make the average turbine capacity to be higher compared to that of onshore installed wind farms. 4.4. Turbine Size Analysis
Under the effects of the marine environment, including soil and wave conditions, offshore WT structure is subjected to a larger loading variation in high wind speeds. 63 Thus, the failure rates of many major subassemblies such as blades and hub, gearbox, generator, structure, and electrical components of offshore WTs are higher than onshore WTs'.
In light of these ambiguous circumstances, the authors in state that adapting the induction machine restrictions while still maintaining an efficient response to an unknown wind speed has been a focus of research for wind turbine systems using a linear time-invariant function.
The demand for and advancement of offshore wind farm technology has led to improvements in every component, resulting in a significant reduction in the specific cost of electricity generation and, consequently, a decrease in LCOE.
