Improved non-dominated sorting genetic algorithm (NSGA)-II in multi-objective optimization studies of wind turbine blades

王珑  王同光  罗源  
【摘要】:The non-dominated sorting genetic algorithm (NSGA) is improved with the controlled elitism and dynamic crowding distance.A novel multi-objective optimization algorithm is obtained for wind turbine blades.As an example,a 5 MW wind turbine blade design is presented by taking the maximum power coefficient and the minimum blade mass as the optimization objectives.The optimal results show that this algorithm has good performance in handling the multi-objective optimization of wind turbines,and it gives a Pareto-optimal solution set rather than the optimum solutions to the conventional multiobjective optimization problems.The wind turbine blade optimization method presented in this paper provides a new and general algorithm for the multi-objective optimization of wind turbines.
