Abstract
This compressed air storage power generation device 10 is provided with: a power demand receiving unit 60; a cold heat demand receiving unit 61; a power supply adjustment device 19 which adjusts the amount of power generated by a generator 15; a cold heat supply adjustment valve 22 which adjusts the amount of cold heat supplied from a first heat medium storage unit 21 to consumer equipment 3; and a control device which controls the power supply adjustment device 19 and the cold heat supply adjustment valve 22 so as to supply the consumer equipment 3 with power and cold heat corresponding to the power demand value and the cold heat demand value.
Claims6
A compressed air energy storage power generation device capable of accumulating renewable energy in a form of compressed air, generating power by using the compressed air as necessary, and supplying power to a consumer facility, comprising:
- a power demand receiving unit which receives a power demand value of the consumer facility;
- a cold heat demand receiving unit which receives a cold heat demand value of the consumer facility;
- an electric motor driven by power generated by use of the renewable energy;
- a compressor driven by the electric motor;
- a pressure accumulation unit which accumulates the compressed air compressed by the compressor;
- an expander driven by the compressed air supplied from the pressure accumulation unit;
- a power generator driven by the expander;
- a power adjustment unit which adjusts the amount of power generated by the power generator;
- a first heat exchanger which cools a first heat medium by exchanging heat between the first heat medium and cold air exhausted from the expander;
- a first heat medium storage unit which stores as cold heat the first heat medium cooled in the first heat exchanger;
- a cold heat adjustment unit which adjusts the supply amount of the cold heat from the first heat medium storage unit to the consumer facility;
- and
- a control device which controls the power adjustment unit and the cold heat adjustment unit so as to supply the consumer facility with the power and the cold heat according to the power demand value received by the power demand receiving unit and the cold heat demand value received by the cold heat demand receiving unit.
