COMPRESSED AIR ENERGY STORAGE: MODELLING

enablers for integrating increasing penetration of renewable energy sources by adding flexibility to the electric power systems. This thesis investigates compressed air energy storage (CAES) as a cost-effective large-scale energy storage technology that can support the development and realization of sustainable electric power systems.

Technology Strategy Assessment

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distributioncenters. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
