This paper presents the mathematical modeling of Compressed Air Energy Storage, (CAES) in obtaining mechanical power generated from expander. Mechanical power is injected to a generator to generate electricity that will stabilize 2MW active power fluctuated caused by intermittent behavior of wind speed. The control system in maintaining dc-link voltage at constant value and control system in supplying generated power from CAES is also discussed here. The goals in using CAES are to smooth out the fluctuated power and increased low power integrated into the grid. This system is analyzed using SimPowerSystem of MATLAB/simulink. Results show that the jCAES is able to not only mitigate generated power but it also can promise constant power generated to grid even at low wind speed.
