Multi-Megawatt Horizontal Axis Wind Turbine Blade Optimization Based on PSO Method

Blade optimization methods are crucial for wind turbine design. In this research, a new set of values the parameters Particle Swarm Optimization (PSO) method is proposed, and its effects on enhancement power generation NREL WP-Baseline 1.5 MW horizontal axis investigated. First, PSO tuned, convergence speed optimal accuracy objective function improved. Then, Class/Shape Transformation (CST) employed, an appropriate order shape polynomial selected. third step, blade optimized according to tuned parameters, airfoil represented by CST algorithms. Later, CFD model, including 37 million cells IDDES turbulence was validated used comparison original blades. The produced more all speeds above 4.5 m/s, with maximum 13.8% at 10 m/s +7.25% rated (11.5 m/s). It should be noted that since algorithms, tunings, techniques adopted in present study were general, presented can as systematic approach aerodynamics multi-megawatt HAWTs.
