摘　　要：全钒液流电池具有功率和能量分别独立设计的优点,因此在电力系统应用中具有显著的优势。本文基于5 kW/10 kW·h全钒液流电池系统,通过恒温、倍功率充放电实验模式,开展全钒液流电池的功率和能量特性的实验研究。功率型应用时,在全SOC范围内以备用SOC曲线为参考基准,其具备对称充放电能量不大于1.35倍额定功率的功率响应能力;能量型应用时,在恒功率充或放电能量基础上,通过不大于0.6倍额定功率充放电最大限度的存储或释放能量。Vanadium redox flow batteries （VRFBs） have power rating and energy durations those are independent of one another, which make them attractive for power systems applications. This paper focuses on the energy and power response capability of the VRFBs, which has been experimentally studied based on 5 kW/10 kW.h system. In power type applications, the reserve SOC curve is a baseline on which the VRFB can respond to less 1.35 times rated power demand with equally charge/discharge energy. In energy type applications, working on a constant-power model, the electrical energy absorbed and supply reach maximum under less 0.6 times rated power.
