Optimization of Ship Bulk Energy Storage Capacity Allocation Based on Improved Genetic Algorithm
Improper configuration of large capacity storage can increase maintenance costs and shorten battery life.Therefore,a genetic algorithm is designed and fuzzy mathematical programming method is added to increase the multi-objective optimization ability of the algorithm.Combined with fuel economy,energy storage device cooling demand power,cost and other indicators,the output situation of diesel generator and battery and energy storage configuration capacity under different working conditions are ob-tained.Taking an electric ferry as an example,the simulation results show that the optimized configuration of the hybrid power sys-tem meets the requirements of ship navigation reliability,the diesel generator can work in high efficiency area,and the fuel con-sumption is reduced by 7.5%.The research results can provide reference for promoting the greening of electric ferry.
