Wind energy conversion using Doubly Fed Induction Generator is one of the most important types of renewable energy generations. Wind farm power output has large fluctuations due to sudden wind speed changes. The proposed topology includes a Battery Energy Storage System (BESS) in the dc link to reduce the power fluctuations on the grid due to the varying nature and unpredictability of wind. The power fed to the grid is always leveled, resulting in an efficient and reliable source of electrical

High performance control of power can be achieved by the proposed scheme, since it facilitates the decoupled control of active and reactive power. The proposed strategy is simulated in MATLAB-SIMULINK under different wind speeds. Placing a BESS in the dc link of a DFIG-based wind energy conversion system, proves to be a satisfactory implementation in terms of maintaining a constant power at the grid.
