Abstract

Abstract: The fluctuation of marine current velocity leads to the fluctuation of power generation. The hybrid energy storage system composed of vanadium redox flow battery and super capacitor is used to improve the power quality and smooth the marine current power generation. With the research and commercialization of large scale power marine current power generation system, the capacity of energy storage system has been increasing. To reduce the rated capacity of super capacitor banks in energy storage system, an energy management strategy based on low-pass filter optimization algorithm of fuzzy control is proposed and the simulation model of 3 MW marine current generation system is built. The simulation results show that the proposed energy management strategy can effectively reduce the rated capacity of the super capacitor banks, avoid the over charge and over discharge of the super capacitor, and keep the state of charge(SOC) of the super capacitor within a reasonable range.
