摘　　要：为弥补电动汽车与电网间能量单向流动不足,提高电动汽车充放电的灵活性与新能源发电的就地消纳能力,提出1种含电动汽车双向无线电能传输的直流微网拓扑结构,研究了将车载电池作为移动储能设备的控制方法。以风光互补发电系统与混合储能为基础,针对双向无线电能传输系统提出基于功率的控制方法,可保证电动汽车作为负荷吸收电能,又可当作储能单位发出电能。为保证系统稳定运行,进一步设计了微网上层中心控制器。Simulink仿真结果表明:电动汽车与电网的能量交互提高了电网运行稳定性,双向无线电能传输可提升电动汽车充放电效果,在一定程度上促进了新能源发电的就地消纳,验证了所提拓扑的有效性与控制策略的优越性。To make up for the shortcomings of one-way energy flow between electric vehicles(EVs)and the grid,improve the flexibility of EVs in the charging and discharging process and strengthen the capability to absorb new energy generation on-site,a DC microgrid topology with bidirectional wireless power transmission(BD-WPT)for EVs is proposed,and a control method of using the EV battery as a mobile energy storage device is studied.This topology is based on a wind-solar hybrid power generation system and hybrid energy storage,and a power-based control method for the BD-WPT system is put forward,which can ensure that the EV can be used both as a load to absorb energy and as an energy storage device to emit energy.To guarantee the stable operation of the system,a microgrid upper-layer central controller is further designed.Simulink simulation results show that the energy interaction between EVs and the grid improves the stability of grid operation,and the BD-WPT system can improve the charging and discharging effects of EVs.To a certain extent,the on-site consumption of new energy power generation is promoted,indicating the effectiveness of the proposed topology and the superiority of the control strategy.
