When asked to define grid-scale energy storage, it’s important to start by explaining what “grid-scale” means. Grid-scale generally indicates the size and capacity of energy storage and generation facilities, as well as how the battery is used.
In off-grid applications, ES can be used to balance the generation and consumption, to prevent frequency and voltage deviations. Due to the widespread use of battery energy storage (BES), the paper further presents various battery models, for power system economic analysis, reliability evaluation, and dynamic studies.
Especially, a detailed review of battery ESSs (BESSs) is provided as they are attracting much attention owing, in part, to the ongoing electrification of transportation. Then, the services that grid-connected ESSs provide to the grid are discussed. Grid connection of the BESSs requires power electronic converters.
