Wind Blade Twist Correction for Enhanced Annual Energy Production of Wind Turbines

Blade geometry is an important design parameter that influences global wind turbine energy harvesting performances. The geometric characteristics of the blade profile are obtained by determining distribution chord and twist angle for each section. In order to maximize production, implying a maximum lift-to-drag ratio speed, this should be optimized. This paper presents methodology numerically determine change in introducing range pitch angles power coefficient case. values were distributed from root tip blade. results prove increases speeds greater than rated point, which improves yearly production 5% compared reference
