Research on energy management of oil-electric hybrid system considering variable load effect
Taking the series structure as the research object of the energy management method of the aviation fuel-electric hybrid system,the energy management was studied according to different load matching forms of the engine.A simulation platform for studying energy management methods was built based on MATLAB/SIMULINK software,whereby the performance of power components was obtained by experiments.The global optimization strategy based on PSO algorithm and the instantaneous optimization strategy based on ECMS were built and applied to the simulation platform.The calculation results showed that after considering the matching form of engine variable load,the fuel consumption under different energy management methods was reduced compared with the constant load,and the global optimization strategy was reduced by 6.27％;the instantaneous optimization strategy decreased by 7.4％.
