Abstract: This paper presents an optimization model for rotor blades of horizontal axis wind turbines. The model refers to the wind speed distribution function on the specific wind site, with an objective to satisfy the maximum annual energy output. To speed up the search process and guarantee a global optimal result, the extended compact genetic algorithm (ECGA) is used to carry out the search process. Compared with the simple genetic algorithm, ECGA runs much faster and can get more accurate results with a much smaller population size and fewer function evaluations. Using the developed optimization program, blades of a 1.3 MW stall-regulated wind turbine are designed. Compared with the existing blades, the designed blades have obviously better aerodynamic performance.

Blade design trade-offs using low-lift airfoils for stall-regulated HAWTs
TL;DR: In this article, the trade-offs in using low-lift airfoils for a 750-kilowatt stall-regulated wind turbine were explored. And the results indicated that reducing the maximum lift coefficient below the upper limit considered in this study increases the cost of energy independently of the wind regime.
