The aim of this paper is to propose controllable torque-speed dependence for power maximization of squirrel-cage-induction-generator-based wind energy conversion system. It uses a vector control scheme and allows imposing both the slope and the zero-torque point of a generator forced mechanical characteristic. A better dynamic, along with extended domain of stable operation and controllable generator torque variations, is thus obtained. Through numerical simulation, closed-loop dynamics and stability analysis are performed for the proposed control method.
