Optimization of HEV System Parameters Based on Hybrid Adaptive Genetic Algorithm

Selecting optimization algorithm is an important part in the optimization of HEV system parameters.To overcome the shortcomings of prematurity and slow convergence speed in simple genetic algorithm, a hybrid adaptive genetic algorithm is proposed.Testing results show that the proposed algorithm has both good whole astringency and fast convergence speed.The new hybrid adaptive genetic algorithm is applied to the optimization of HEV system parameters and satisfactory optimization results and convergence effects are obtained.Based on the optimization results, an engine/generator set of a series hybrid electric mini-bus is designed optimally.
