An electric power system is a network of pieces that combine to process and distribute electrical power. While this can take many forms, the most common are the large networks – sometimes known as "the grid" – that supply communities with electricity. These networks typically contain a source – usually a generator – which creates power that is passed through a transmission
The preceding results suggest that uptake of renewable energy in the grid, corresponding to increasingly distributed power generation, can lead naturally to improved grid function insofar as synchrony is concerned.

The generation side of a power grid mainly operates with high-voltage electricity across a long distance. Generally, the RE systems are utilized as a distributed energy resource (DER) system at the distribution side, whereas the usage of RE systems at the generation side is rarely found with ESS-integrated power grids.
Electricity is used to compress air and store it in either an underground structure or an above-ground system of vessels or pipes. When needed the compressed air is mixed with natural gas, burned and expanded in a modifi ed gas turbine. Typical underground storage options are caverns, aquifers or abandoned mines.
