Application of VRB Technology in the Energy Storage System of a Micro-grid

As the critical technology of micro-grid,the energy storage technology have a significant effect on supply reliability,economy and security of micro-grid. The paper aims to enhance power quality and stability of micro-grid through equip the micro-grid with vanadium redox battery( VRB) storage system. Firstly,It analyzes the character of the current energy storage technologies and introducse VRB operating principle. Secondly,It establishes equivalent circuit model. Finally,analyzes on charge and discharge character by MATLAB / Simulink.
