Abstract

Energy storage is an emerging technology that can provide flexibility for the electrical power system operation, especially in the conditions of large scale penetration of highly intermittent renewable energy sources. The paper gives an overview of energy storage technologies, giving the main technical characteristics and comparison of different energy storage features, like specific energy and power, price, number of cycles, expected lifetime, etc. Basic requirements for the connection of production and load facilities to the transmission network are described, as well as challenges regarding energy storage transmission grid integration. Finally, worldwide examples of energy storage grid connection projects are given.
