Abstract: For large power wind turbines, large-signal disturbance in wind power converter require a sufficiently large stability region around the quiescent values. The nonlinear and uncertain variations in power converter lead the control difficulty. In this paper, we will discuss the control strategy and 3 hierarchies in Power Electronic Building Blocks (PEBBs) after analyzing non-linear and uncertain variation of power semiconductor devices. A potential function based Lyapunov function will be introduced.

Keywords: Doubly fed induction generator, uncertainty, nonlinear, locally stable, global stability
