摘　　要：储能系统是风力发电系统和太阳能光伏发电系统的重要组成部分,钒液流电池(VRB)作为一种新型储能电池,其优势及成功范例充分展示了它在储能市场的广阔前景。介绍了钒液流电池的工作原理,通过研究VRB的堆栈电压、荷电状态SOC、内部损耗和动态响应,构建了VRB仿真系统模型。详细研究了VRB恒电流充放电模式,定性、定量地分析了影响钒液流电池储能充放电效率的因素,并得出了最优充电电流。The energy storage plays an important role in wind power systems and solar photovoltaic power generation system. As a new energy storage battery, the vanadium redox flow battery （VRB）＇s advantages and successful example demonstrate its broad prospects in storage marker. The operating principle of VRB was introduced. Through studying stack voltage, state of charge, internal loss and dynamic response, VRB simulation model was set up. The constant current mode for VRB was studied in detail. At the end, the factors which influenced the charging and discharging efficiency of battery energy storage were analyzed qualitatively and quantitatively. What＇s more,the optimal charging-discharging current was obtained.
