DEVELOPMENT AND DEMONSTRATION OF COMPRESSED AIR ENERGY STORAGE SYSTEM FOR POWER COMPENSATION OF INTERMITTENT RENEWABLES

Abstract

The pilot plant of CAES has maximum power for charge and discharge of 1,000kW and energy storage capacity of 500kWh and 52 of compressed air tanks have a capacity of 30.5m3. They are used at a pressure between 0.30 to 0.93 MPaG. Via adjustment of control systems and official inspection, the construction has completed in the end of April, 2017. Waseda University and The Institute of Applied Energy operate the plant for 2 years from FY2017. Characteristics of the plant are measured at first followed by validation of newly developed control technologies using wind power prediction information.
