Do compressed air energy storage systems operate under off-design conditions?

Compressed air energy storage (CAES) systems usually operate under off-design conditions due to load fluctuations, environmental factors, and performance characteristics of the system. Thus, to improve design and operation characteristics, it is important to study off-design performance of CAES systems.

What are the advantages and disadvantages of compressed air energy storage?

1. Introduction Compressed air energy storage (CAES) systems have the advantages such as large scale, low cost, and possess a flexible storage duration as well as a long lifespan, and two commercialized CAES plants (McIntosh and Huntorf) are in operation , .

Why should a multi-stage gear coupled system use EPR?

Moreover, the temperatures of outlet water are approximately the same, avoiding large exergy loss from the water mixing process. Under multi-stage gear coupled configuration, EPR operation can help to improve the stability of system.

How do you calculate eair & ehot_water in a multi-stage compressor?

(14) η E, C = E air + E hot_water W total,c where Wtotal,c is the total work consumed by the multi-stage compressor, Eair is the exergy of high-pressure air at the outlet of the multi-stage compressor, and Ehot_water is the exergy of hot water in the compression process.

How does Mr affect exergy efficiency?

For a given value of BP, a point of MR exists where the exergy efficiency has no obvious improvement in the OVRA operation compared to that of the EPR operation. When MR is changed from this point, the exergy efficiency improves markedly for the OVRA operation. The efficiency can increase by, at most, 2.5% within the range of calculation.
