Large-scale stationary storage systems ("front-of-the-meter-storage") can serve as short-term storage systems to make large amounts of renewable electricity quickly accessible to the power grid. They can also be used to increase the transmission capacities of the power grids, thereby reducing the need for grid expansion. Equipped with grid-forming converters, large-scale storage systems will play a key role in the dynamic stabilization and control of power grids in the future. Large-scale storage systems will be needed to take over the grid-forming tasks (voltage and frequency control) carried out today by the conventional must-run power plants. These storage systems can also store large quantities of surplus renewable electricity temporarily, feeding it later into the grid at a profit when demand is high.
The significant expansion of large-scale stationary battery storage, especially in conjunction with photovoltaic power, holds great potential. The stored PV electricity can be fed into the interconnected grids in line with demand, thus optimizing yield. In addition, large-scale storage systems can be set up at former, conventional power plant sites, making use of these existing connections to the power grid. In the future, such large-scale storage facilities will play an important role in grid stability and security of supply.
