OPTIMIZITION DESIGN OF ALL-VANADIUM REDOX FLOW BATTERY ENERGY STORAGE SYSTEM
The redox active substance of all-vanadium redox flow battery (VRB) is stored in two separate tanks. In the pumped circulation,the solution flows through the battery,oxidation-reduction reaction takes place on the electrode in both sides of the ion exchange membrane. Compared with other kinds of secondary batteries,VRB has its own characteristics. The arrangement and design of VRB are very flexible,which largely benefit the association of different modules,and make the capacity of the battery may be large or small as the customer’s wish. The battery system can respond at a high speed and output great power. The battery system is safe,stable and easy to maintain. Self-discharging is slight. Has a long life-cycle,high efficiency and cheap price,etc. As a high-power power electronic equipment,the arrangement of PCS should pay special attention on the heat dissipation system. According to the actual power and structure of PCS,maybe take some electromagnetic shielding measure in the equipment room. Control and supervision system should be optimal designed,including BMS and other subsystems. Because there are not domestic regulations of arrangement and design about VRB ESS yet in China,in the future,should summarize experience in time from the actual projects,in order to promote the popularization and application of VRB technology in aspects as electric energy storage and sers spare power.
