摘　　要：储能技术的不断进步,为未来配电网的发展提供了新的思路。提出了一种未来配电网的可能形态——基于储能装置、以用户为单位的低压直流微电网。同时论述了该形态配电网的结构特征和优越性以及当前技术与这个设想之间的差距。在当前技术水平下,低压直流微电网和储能装置的充放电管理领域的技术已经能够满足设想需要,但是储能装置的能量体积比和能量重量比以及寿命还存在较大差距。随着储能技术的不断进步发展,未来配电网必将发生革命性的变革。At present,energy storage technology has provided new development ideas for the future architecture of power distribution networks.This paper proposes a possible future architecture of distribution systems-low-voltage direct current micro-grids based on energy storage systems.It also discusses the features and advantages of this architecture of power distribution network,and the gap between current technology and this surmise.It concludes that the technology of low-voltage DC micro-grid and energy storage devices can already meet the technical needs,but there are still large gaps in the energy-volume ratio,energy-mass ratio and life span of the energy storage devices.With the development of energy storage technology,the future distribution network will have huge changes necessarily.
