A NEW CONTROL STRATEGY FOR DFIG BASED WIND ENERGY SYSTEM USING BESS

This paper presents a new control strategy for a grid connected Doubly Fed Induction Generator (DFIG).In order to decouple the active and reactive powers generated by the machine, stator - flux oriented vector control is applied. High performance control of power can be achieved by the propo sed scheme, since it facilitates the decoupled control of active and reactive power. The proposed topology includes a Battery Energy Storage System (BESS) 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 power to the grid. The proposed strategy is then simulated in MATLAB - SIMULINK and the developed model is used to predict the behavio
