Power smoothing control for wind farms using flywheel based energy storage

This paper proposes the use of a flywheel based energy storage device at the power output end of wind farms. A control strategy is put forward based on the characteristics of both wind farms and flywheels. The proposed system is simulated in the Matlab/Simulink environment. The results show that the proposed control strategy could attain the target of smoothing grid side active power and reduce fluctuations of active power.
