Abstract
Energy storage technologies are becoming ever more important in power systems because of the increasing implementation of renewable energy sources as well as their technical, economic and environmental benefits. It is important to understand how these technologies operates, their characteristics, their effect on the traditional grid system and how they can be effectively utilized for industrial, domestic and commercial customers. This paper aims to provide an overview of the existing energy storage technologies and demonstrate how they are being employed efficiently in power systems. A comparison of various energy storage devices, system requirements and classification of energy storage technologies in terms of response rate, life cycle, operational cost and their energy capabilities will be addressed.
