The aim of this paper is to analyse the closedloop stability of a squirrel-cage-induction-generator-based wind energy conversion system equipped with an improved power optimization control law. This control imposes a dependence between the generator torque and its rotational speed, thus heavily modifying the system dynamics and control efforts. A stability analysis made through numerical simulation gives the operating limits of the proposed control.
