The Application of Various Energy Storage Technologies in Modern Smart Grid with Comparative Study

In recent days, a wide variation of load demand is observed in power system. Furthermore, the introduction of various renewable energies into the grid has imposed a great challenges to the power grid operators. In this context, the energy storage technologies (ESTs) play a major role for managing the load variation as well as generation variation. This paper presents a brief review of the different ESTs and their role in the implementation of smart grid. The comparison of the various characteristic parameters such as life cycle, self-discharge, energy density, efficiency, technological maturity, etc. of the different EST are also highlighted. Furthermore, the architecture and features of the smart grid are also presented. The different challenges and possible recommendations for implementation of smart grid are also outlined. In a nutshell, this article will provide a clear guideline about the application of different ESTs in modern smart grid.
