N2 - This paper presents an adaptive power-sharing methodology for management of dc microgrids powered by fuel cell (FC) and storage system (SS). In this context, the use of an adaptive k -sharing function in the control scheme is proposed to compensate the fast transients on the ac-side and manage the power sharing at steady-state regime between the FC and SS. The adaptive k -sharing is implemented with a low-pass filter transfer function for the FC and a complementary transfer function associated with the adaptive k -sharing gain for the SS. The proposed adaptive k -sharing function links the FC and the SS dynamics with the management of the dc microgrid, ensuring that the entire FC operation is performed in accordance with its operational limits. One of the main advantages of the proposed adaptive k -sharing is to reach high levels of stability and minimum disruptions on the FC terminals. To evaluate the feasibility of the proposed approach, we analyze the k -sharing behavior to determine the operational limits of the dc microgrid. Finally, to support the theoretical analysis we carried out a set of experimental results.
