Abstract：Distributed energy has been widely developed and applied. Distributed generations(DGs) are mostly unstable electric sources, so a unified model in which energy storage systems are connected to the DC bus is proposed in this paper. Energy storage unit can stabilize energy fluctuation of DGs and improve power qualities. It is connected to DC bus through interleaved bidirectional DC/DC converter. In traditional occasions the inductor ripple of bidirectional DC/DC converters tend to be high and the inductor current of different phase are usually unbalanced. This paper proposes a novel phase-shifted current sharing control strategy to solve these problems. Experimental results are conducted to validate the effectiveness of the proposed strategy.
