With growing penetration of renewable sources in the power scenario there is also a bilateral increase for the need of storage systems. Unpredictability and high intermittence in the power generated from renewable systems like wind have driven the need for adequate back up energy reserves and power quality improvement according to grid standards. Battery Energy Storage Systems (BESS) have been the most popular and mature technology for grid applications from a long time. Lot of research is pursued in BESS to develop its volumetric capacity, specific discharge rates and efficiency by improving the material properties, integration topologies and control mechanisms. Still there is huge scope for improving these systems to deliver maximum penetration results. This paper explores the various BESS available, their developments, properties as well as the applications in Wind Power grids. Also, a brief overview of the future scope of development in BESS is outlined. © 2014 IEEE.
