摘 要：In this paper,a dual droop-frequency diving coordinated control strategy is proposed for electric vehicle(EV)applications,where the hybrid energy storage system(HESS)with supercapacitors and batteries is integrated to prolong the life time of storage *** dynamic power allocation between the supercapacitor and batteries are obtained through the voltage cascaded control,upon which the high and low frequency power fluctuation are absorbed by the supercapacitors and batteries respectively to fully exploit the advantages of the supercapacitors and ***,the power capacity is scaled up by connecting storage blocks in parallel.A dual droop control scheme for parallel-connected energy storage system and its operation principle is introduced on the aspect of current sharing characteristic and state-of-charging(SOC)*** detailed analysis and formula derivation,the corresponding loop parameters are *** this control method,the current sharing performance is ensured and each block makes the self-adaptive adjustment according to their ***,the load power can be shared effectively,which helps to avoid the over-charge/over-discharge operation and contributes to the life cycle of the energy storage *** module is autonomous controlled without the necessity of communication,which is easy,economic and effective to ***,the simulation and experimental results are exhibited to verify the effectiveness of the proposed control scheme.
