摘　　要：能量路由器是支撑能源互联网的核心智能装置。针对具有配电网、光伏、储能、直流输出、多个电动汽车充电桩接口的配电网能量路由器,通过直流母线电压信号的协调控制,实现充分利用光伏发电的目的。为解决多台电动汽车接入能量路由器时过度充电和放电影响电动汽车锂电池寿命问题,采用SOC均衡控制,以电动汽车锂电池的荷电状态(SOC)作为控制对象,实现多电动汽车输出功率的均衡,以期延长电动汽车锂电池的使用寿命。仿真表明,论文提出的控制方案在实现直流母线电压稳定控制的同时,能实现与能量路由器相连的电动汽车锂电池SOC均衡控制,控制效果良好。Energy router is the core intelligent device to support energy Internet.The energy router of the distribution network with distribution network,photovoltaic,energy storage,DC output and multiple electric vehicles charging pile interfaces achieves the maximum photovoltaic consumption through the coordinated control of DC bus voltage signals.To solve more than one electric vehicle access energy router when excessive charging and discharging energy problem affecting the service life of electric cars,lithium batteries,SOC balance control is adopted.The state of charge(SOC)of lithium battery of EV is taken as the control object to achieve the balance of output power of multiple EV,so as to extend the service life of lithium battery of EV,realize the balance of electric power output.The simulation results show that the proposed control scheme can realize the SOC balance control of EV lithium battery connected with energy router while realizing the DC bus voltage stability control and the control effect is good.
