The application scenarios of energy storage technologies are reviewed and investigated, and global and Chinese potential markets for energy storage applications are described. The challenges of large-scale energy storage application in power systems are presented from the aspect of technical and economic considerations.
The energy storage system applications are classified into two major categories: applications in power grids with and without RE systems and applications in detached electrification support. This section presents an extensive discussion of the applications of various ESS.
Energy storage technologies can potentially address these concerns viably at different levels. This paper reviews different forms of storage technology available for grid application and classifies them on a series of merits relevant to a particular category.
The application of energy storage technology in power system can postpone the upgrade of transmission and distribution systems, relieve the transmission line congestion, and solve the issues of power system security, stability and reliability.
ESS can support the system by providing reactive power to control the output. Sometimes, the ESS can support the power grids at the generation side by absorbing the overplus energy to prevent output spikes. ESS can also deliver the stored energy to recover the output drop.
As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
