| Abstract |
This paper presents a study and experimentation
of a hybrid energy storage system prototype, based on
Compressed Air, where the charging and discharging is
done within maximum efficiency conditions of the
volumetric machine. As the maximum efficiency conditions
impose the level of the converted power, an intermittent
time-modulated operation mode is applied to the
thermodynamic converter to obtain a variable converted
power. A smoothly variable output power is achieved with
the help of a supercapacitive auxiliary storage device used
as a filter. The paper describes the concept of the system,
and reports on the calculated energetic efficiency
performance, as well as measured on a first prototype
system. |
