Abstract

Global needs for energy is increasing day by day. This has promoted increased penetration of renewable energy into the grid. Increasing use of renewable energy systems and its technological advancement has led to the emergence of storage as a crucial element in energy management. This has also changed the traditional way of load balancing. Intermittent nature of these sources introduces errors in the grid. In order to make these sources more reliable, an energy storage system will be the most crucial factor. Electricity storage can be viewed as a key solution to overcome a number of technical and financial issues in the integration of renewable energy sources with the grid due to its unique capacities to store, absorb and later injecting electricity again. The objective of this paper is to compare existing storage technologies and new advancements based on their main performance parameters suitable for the application. The comparison shows that each technology differs from other in terms of ideal system application environment and energy scale of storage. Hence it is very important to study different storage systems for optimum integration with the grid. This article is an overview of recent undertakings that represent storage as a reliable solution for stable and cost effective operation of microgrid. The objective of this article is to stimulate conversation about storage technologies among interested parties and to learn how users feel about various challenges related to the deployment and use of grid level storage technologies.
