A compressed air energy storage power generation device includes an inert gas source for supplying an inert gas, an inert gas flow path system, and a flow path switching unit. The inert gas flow path system fluidly connects the gas phase portion of the high temperature heat storage unit, the gas phase portion of the low temperature heat storage unit, and the inert gas source. The flow path switching unit switches the inert gas flow path system to at least a state in which the inert gas source is in communication with both the high temperature heat storage unit and the low temperature heat storage unit and a state in which the inert gas source is blocked from both the high temperature heat storage unit and the low temperature heat storage unit.

A compressed air storage power generation apparatus is provided with a motor, a compressor, a pressure accumulation tank, an expander, a generator, a first heat exchanger and a cold heat extracting unit. The motor is driven by input power generated using renewable energy. The compressor is mechanically connected to the motor and compresses air. The pressure accumulation tank accumulates the compressed air compressed by the compressor. The expander is driven by the compressed air supplied from the pressure accumulation tank. The generator is mechanically connected to the expander. The first heat exchanger exchanges heat between the compressed air supplied from the compressor and a heat medium and cools the compressed air to room temperature. The cold heat extracting unit extracts air serving as working fluid as cold air of the room temperature or lower. Due to this configuration, the compressed air energy storage power generation apparatus capable of smoothing input power that varies irregularly and efficiently performing heating and cooling with the input power is provided.

A compressed air energy storage power generation device includes a first heat exchanger, a heat storage tank, a second heat exchanger, a heating unit, a first power distributor, and a controller. The first heat exchanger performs heat exchange between the compressed air from a compressor and the heating medium. The heat storage tank stores the heating medium heatexchanged by the first heat exchanger. The second heat exchanger performs heat exchange between the compressed air from an accumulator tank and the heating medium from the heat storage tank. The first power distributor distributes the generated power of the power generator to a power system and the heating unit. When the internal pressure of the accumulator tank reaches a predetermined pressure and the generated power is larger than the power demand, the controller supplies a part or all of the generated power to the heating unit by the first power distributor.
