Abstract
Energy storage systems (ESSs) are desired and widely applied for power smoothing especially in systems with renewable generation and pulsed loads. High-pass-filter (HPF) is commonly applied in those applications in which the HPF extracts the high frequency fluctuating power and uses that as the power reference for ESS. The cut-off frequency, as the critical parameter, actually decides the power/energy compensated by ESS. Practically the state-of-charge (SoC) of the ESS has to be limited for safety and life-cycle considerations. In this paper an adaptive cut-off frequency design is proposed for systems with multiple ESS units to realize several objectives simultaneously including SoC limiting, SoC balancing and power smoothing. Experiment is conducted considering a pulsed load profile. The results demonstrate the effectiveness of the proposal concerning the mentioned control objectives.
