"Firming" solar generation – Short-term storage can ensure that quick changes in generation don''t greatly affect the output of a solar power plant. For example, a small battery can be used to ride through a brief generation disruption from a passing cloud, helping the grid maintain a "firm" electrical supply that is reliable and consistent.
With the rapid growth of renewable generation in power system, the share of dispatchable power reduces, raising the need for large-scale energy storage to compensate for volatile renewable output. Advanced adiabatic compressed air energy storage (AA-CAES), advantageous in large capacity and emission-free, is promising for
