Fuzzy Logic Based Control Of Variable Wind Energy System

Abstract

Wind energy has a high penetration in smart grid applications. Accurate communion of the wind energy conversion system and the present grid is thereby required. A new control plan is presented in this paper for the coordinated operation of variable speed wind energy conversion in smart grid applications. A variable speed wind energy conversion system using Squirrel- cage Induction Generator is studied. From the information gathered a system is designed and analyzed under fault. The system works with total coordination as the controllers and converters are appropriately designed. A droop controller is used during fault which regulates the torque and speed of the generator thus limiting the generation. Further, for performance betterment, a fuzzy controller is incorporated for the optimization of the output power of the wind turbine with wind speed variation. There is an increase of the voltage at the DC link and in the speed of the generator with the proposed controller.
