Electrolyte flow rate control for vanadium redox flow batteries using the linear parameter varying framework

In this article, an electrolyte flow rate control approach is developed for all-vanadium redox battery (VRB) system based on the linear parameter varying (LPV) framework. The regulated to provide a trade-off between stack voltage efficiency and pumping energy losses, so as achieve efficient operation. nonlinear process model embedded in state–space description set of state feedback controllers are designed handle fluctuations current during both charging discharging. Simulation studies have been conducted under different operating conditions demonstrate performance proposed approach. This was further implemented laboratory scale VRB system.
