Abstract

This paper presents an economical and experimental study of large and small scales Compressed Air Energy Storage (CAES) integrated with PV array and wind turbine generator based on economic criteria. Two different CAES systems with three different case studies are presented in detail. The first model included wind turbine, compressor, and storage reservoir with different rating values, 220 MW, 200 MW, and 150,000 m3 for the turbine, compressor, and storage reservoir volume respectively. A small CAES power system consists of 5 KW isolated load fed by Bergey Excel-S 10 kW wind turbine is chosen as another application to investigate the effectiveness of the proposed presented model. The second presented model is based on real prototype testing and laboratory measurements supplied from a PV panel. A prototype model is built up in a small size to indicate the system characteristics and its main effective parameters. Furthermore, a case study on an isolated Egyptian village (Halayeb) is introduced as a third case study based on the basics of the proposed prototype system. The results prove the ability of the CAES system to supply domestic loads of a grid isolated village. Finally, the paper presented an economic analysis of the presented system.
