	The Fast Direct Power Control Strategy of Dual Active Bridge Converter for Energy Storage System in DC microgrid   By Zhongxiu XIAO, Wanjun LEI, Yilin YIN, Wei MU	[View]   [Download]
Abstract: This paper proposes a fast direct power control method (FDPC) with single-phase-shift control to directly control the power flow rapidly and accurately for the dual active bridge converter in the energy storage system. The strategy makes the converter realize rapid and precise output power regulation under the following conditions, including load step-change, the desired output power step-change, and voltage fluctuations. An accurate discrete-time model is applied to analyze the system's dynamic characteristics. It is also independent of circuit parameters such as inductance, which can improve compatibility and portability. Finally, by comparing the FDPC method with the traditional PI feedback control, the superiority of the proposed strategy is verified through theoretical analysis and experimental results, which demonstrates its application prospect in the field of electric energy dispatch control of the DC power supply network.
