Grid Energy Storage Systems

Abstract

In this chapter, a complete analysis of major technologies in ESSs and theirpower conditioning system for connecting to the smart grid is performed. The study includes the principle of operation and the technology profile of conventional and leading emerging storage topologies suitable for SG applications. The analysis examines opportunities for energy storage to clearly influence the generation, transmission and distribution of electricity in the new context of the smart grids. Furthermore, it discusses the design and implementation of power electronic applications and their control strategies for these storage technologies. To this aim, after this introduction to the topic, the application of energy storage in smart grids is introduced in Section 10.2. Thereafter, Section 10.3 describes an overview of energy storage technologies. Section 10.4 discusses the assessment of energy storage technologies for smart grid applications. Based thereon, the power conditioning system for interfacing energy storage technologies with the smart grid and its controller are presented in Section 10.5. Lastly, the chapter concludes with a discussion presented in Section 10.6.
