Modeling of wind energy system with MPPT control for DC microgrid

The paper proposes wind energy conversion system modeling with the help of MATLAB Simulink for dc microgrid application. For tracking maximum power available in wind energy, MPPT (Maximum Power Point Tracking) technique is used. The proposed system contains the wind energy conversion model, 3-ph diode bridge rectifier model, MPPT controller and DC-DC converter (Buck converter) model. The DC-DC converter model (buck converter) permits the output of MPPT controller i.e. duty cycle to make adjustment in input voltage of converter for tracking maximum power point from wind generator. The major advantages of the designed system are circuit simplicity as well as simple control algorithm for supplying power to dc microgrid. By making comparison to the system without MPPT control, system with MPPT control gives greater output power.
