Abstract : The rapidly increasing energy demand is compelling the humankind for an alternative source of electrical energy generation and that leads to one thought, which is nothing but employing renewable energy generation. The incorporation of renewable energy generation into the existing grid system overlooks at some of the technical challenges and difficulties. The modern wind power plants use the methodology of Doubly Fed Induction Generator (DFIG) based Wind Turbine Generator (WTG). This framework focuses on the performance of a new control mechanism incorporated with grid fused DFIG based WTG. The fuzzy-based Rotor Side Converter (RSC) is developed to achieve maximum power delivery from DFIG using slip frequency control mechanism. To assist the slip frequency control, the PI-based Grid Side Converter (GSC) of DFIG is also proposed to maintain constant DC link voltage under grid voltage variations. The efficacy of the controller is validated using MATLAB/Simulink for the different operating conditions such as varying wind speed, grid voltage variations, etc. A unique feature of the controller is that it adapts to variations in wind velocities for achieving Maximum power output. The laboratory prototype model of RSC and GSC converter controller is developed and the hardware setup along with the results are examined.
