Overview of Energy Storage Technologies: A Techno-Economic Comparison

摘要

This paper presents the necessity of energy storage technologies to help the Renewable Energy Resources (RERs) power the smart grid to meet the energy demands of the future. The paper identifies the different storage techniques that can be implemented in to a smart grid and a cost-benefit analysis of the different storage techniques. While explaining these different storage techniques the following items that will be covered are size, technology, protection, advantages, disadvantages, time scale for implantation and physical location of the storage. The cost-benefit analysis of different storage technologies have also been presented in this paper, the guidelines are also presented to select a storage technique based on a given power systems problem.
