| Abstract: | Due to the perfor-mance characteristics of battery and super capacitor,a coordinated control strategy based on hybrid energy storage of battery and super-capacitor is proposed. The fluctuating power is separated into low frequency and high frequency by low-pass filter. The low frequency part is suppressed by the battery. The high frequency part is suppressed by the super capacitor. A voltage and current double closed-loop coordination controller is further designed to realize the frequency division energy through out of the battery and the super capacitor. The simulation results show that the proposed hybrid energy storage system effectively suppresses the power fluctuation of wind power system and prolongs the service life of the battery. |
