Performance analysis of industrial steam turbines used as air expander in Compressed Air Energy Storage (CAES) systems

Modeling and control of an open accumulator Compressed Air Energy Storage (CAES) system for wind turbines

This paper presents the modeling and control for a novel Compressed Air Energy Storage (CAES) system for wind turbines. The system captures excess power prior to electricity generation so that electrical components can be downsized for demand instead of supply. Energy is stored in a high pressure dual chamber liquid-compressed air storage vessel. It takes advantage of the power density of hydra...

Combined Optimal Design and Control of a near Isothermal Liquid Piston Air Compressor/expander for a Compressed Air Energy Storage (caes) System for Wind Turbines

The key component of Compressed Air Energy Storage (CAES) system is an air compressor/expander. The roundtrip efficiency of this energy storage technology depends greatly on the efficiency of the air compressor/expander. There is a trade off between the thermal efficiency and power density of this component. Different ideas and approaches were introduced and studied in the previous works to imp...
