Study of V2G Control for Driving Multiplexed On-board Energy Storage Converters

电动汽车充电技术伴随着电动汽车的日益普及而得到长远的发展。车载储能变流器由于其不需要充电桩支持,具有即插即用的特性而受到关注。其中,复用驱动电机和驱动变流器组成驱动复用型车载移动储能的方案由于具有较高的系统集成度和功率密度,在近些年受到了广泛研究。该系统具有能量双向流动控制能力,在配电网下进行车辆到电网(V2G)操作可以为配电网提供额外的储能容量。此处提出了驱动复用型车载储能变流器拓扑结构,并提出一种适应配电网的V2G工作模式和相应控制策略。搭建的样机证明了方案的可行性。

Electric vehicle charging technology has been developing in the long run along with the increasing popularity of electric vehicles.On-board energy storage converters are attracting attention because of their plug-and-play feature without the support of charging piles.Among them,the multiplexed driving motor and driving converter to form a driving multiplexed on-board mobile energy storage solution has been widely studied in recent years due to its high system integration and power density.This system has the ability to control energy flow in both directions,and vehicleto-grid(V2G) operation under the distribution grid can provide additional energy storage capacity for the distribution grid.A driving multiplexed on-board energy storage converter topologic structure is proposed,and a V2G operation mode and corresponding control strategy adapted to the distribution grid are proposed.The built prototype demonstrates the feasibility of the scheme.
