Grid energy storage, also known as large-scale energy storage, are technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed.
In this method, each storage system has responsibility for the control and optimization of the power output of the source to which it is connected , , . The aggregated model operates so that the whole system—for example, a microgrid (MG)—is supported through a central energy storage system.
Grid-scale storage refers to technologies connected to the power grid that can store energy and then supply it back to the grid at a more advantageous time – for example, at night, when no solar power is available, or during a weather event that disrupts electricity generation.
In distributed arrangements, the energy storage systems are connected via individual power electronic interfaces to each RES. In this method, each storage system has responsibility for the control and optimization of the power output of the source to which it is connected , , .
The available technologies and applications of energy storage system in the modern grid. The possibility of integrating different types of energy storage system into the modern grid. Batteries are the most commonly used technique to cover many applications. Batteries can integrate with most other storage types to provide system support.
As of 2023, the largest form of grid storage is pumped-storage hydroelectricity, with utility-scale batteries and behind-the-meter batteries coming second and third. Lithium-ion batteries are highly suited for shorter duration storage up to 8 hours. Flow batteries and compressed air energy storage may provide storage for medium duration.
