Beschreibung
Zusammenfassung:A compressed air energy storage and power generation method comprises: driving an electric motor (32) by fluctuating input power; compressing air by a compressor (10) mechanically connected to the electric motor (32); storing the compressed air, which is supplied from the compressor (10), in an accumulator tank (12); driving an expander (16) by the compressed air supplied from the accumulator tank (12); generating power by a generator (30) mechanically connected to the expander (16), defining, as a reference storage value, a storage value indicating that a storage amount of the air in the accumulator tank (12) is in a predetermined intermediate state; controlling at least one of the electric motor (32) and the generator (30) in function of the storage value.
