Summary:This paper presents comparative experimental measured results and computer simulated outcomes of a vanadium redox flow battery (VRFB)-based energy-storage system (ESS) under different charging and discharging conditions. The experimental platform of the studied VRFB-based ESS includes an experimental VRFB of rated 500 W, a battery monitoring instrument, a programmable DC power supply, a single-phase DC-to-AC power inverter, an AC load, and a power-resistor load. The parameters of the equivalent-circuit model of the studied VRFB are carefully derived according to the obtained experimental measured results. From the comparative measured and simulated results, it shows that the average errors of voltage and power of the studied VRFB-based ESS under various charging and discharging conditions can be as low as 0.5053% and 1.232%, respectively.
