Vanadium Redox Battery System and Its Energy Storage Application in Wind Farm

The energe storage system with combination of large-scale grid-connected wind farms will be the developing trend of renewable energy in future. The flow battery has becoming the most potential advanced chemical energy storage technology among the storage method. This paper is mainly introducing about the work principle, characteristics and structure of the VRB system. Futhermore, the control mechanism of the power quality and stability used in wind farm connected to power grid by battery energy storage is illustrated in the end of paper.
