Abstract: An improved genetic algorithm combined withniche algorithm and immune algorithm is proposed to solve the standardgenetic algorithm for prematurity and slow convergence rate.On one hand,vaccine is introduced to guide the generation ofinitial population, so the individual has some excellent gens which will reduce the optimal time, and an adaptive updating mechanism ofvaccine and parameterscope is proposed as the wind speed data renewed. On the other hand, niche genetic algorithm is adopted to keep thediversity of evolution population. Examples show that it is feasible to apply the proposed methodinshort-term wind speed prediction, with higherforecasting accuracy and convergence speed.
