This study proposes an optimal trailing edge serration design for wind turbine rotor blades. Flow control devices can improve aerodynamic and aeroacoustics performance, load reduction, fluctuation suppression, and ultimately increase wind turbine power output. The viability of the solution on an application is assessed using the Weibull distribution of wind in three selected regions. Results show that the presence of serration is capable of improving the annual power generation in all the investigated cities by up to 12%. Further studies in this area can cover the mechanical aspect and aero-acoustic impact of the trailing edge serrations as well as the correlation between acoustic emission, power generation, and aerodynamic forces in the improvement of an overall wind turbine performance.
