An Introduction to Energy Storage Technologies. Paul Breeze, in Power System Energy Storage Technologies, 2018. Abstract. Energy storage plants take energy from generating stations and store it for later use. Large storage plants can operate at the transmission grid level while the smallest can offer storage services to small commercial and residential consumers.
This suggests an accurate modelling of LAES is necessary for multi-mode operation, in agreement with the conclusions drawn for a compressed air energy storage plant in Ref. [41]. The more services LAES is providing, the more revenue is lost for the corrected case, due to frequent off-design discharge (see section 3.4 ).
