Abstract

In order to solve the problem of energy storage system state of charge (SOC) adjustment

this paper proposes a storage SOC management strategy for the variant filter time constant of the low pass filtering method

with the fluctuation harmonic content (FHC) and the battery equivalent cycle life introduced to evaluate the effect of management strategy. First

the impact of fluctuations on wind power is analyzed in the frequency domain from the perspective of power system operation to provide a basis for the management strategy. Then

the principles and control structure of the proposed management strategy are given

and the control rules of variable time constant of low pass filter and charge-discharge power limiting strategy are designed on the basis of the power fluctuation frequency analysis. Finally

a simulation example is designed to verify the validity of the proposed SOC management strategy by the FHC and the battery equivalent cycle life. The effectiveness of the strategy is verified by simulation results. This work is supported by National Natural Science Foundation of China (No. 61201010) and National High Technology Research and Development Program of China (863 Program) (No. 2013AA051002).
