Paragraph starter

This investigation into the effect of pitch angles on wind turbine performance, as demonstrated by Roul and Kumar (2020), highlights that blade pitch is a critical factor in optimizing energy capture. Their CFD simulations revealed that while higher wind speeds increase torque, increasing the pitch angle reduces it, with an optimal angle identified for maximum power generation. This suggests that dynamic pitch control is vital for maximizing the efficiency of wind energy systems.
