Study and Dimensioning of a Compressed Air Storage System Dedicated to the Isolated Site

While the majority of primary energies (gas, oil or coal) are easily stored, it is very difficult to store electricity in large quantities. However, it is possible to convert it into other forms of intermediate and storable energies (potential, kinetic, chemical or thermal).In this paper the storage system chosen is Compressed Air Energy Storage (CAES), which consists the use of available electricity at low cost during periods of low consumption, To store air in underground cavities (former salt mine or natural gas storage cave) by means of a compressor. At the moment of consumption peak, this compressed air is released to turn turbines which thus generate electricity. Then the different types of existing compressors will be presented and the sizing of the compressor dedicated to the compression chain will be described.
