A Novel Control Strategy of MPPT Taking Dynamics of Wind Turbine into Account

This paper presents a novel Maximum Power Point Tracking (MPPT) strategy in Wind Generator System (WGS) for the optimization of wind conversion efficiency in both steady and dynamic state. The strategy combines the idea of Power Signal Feedback (PSF) control and Input-Output Feedback Linearization method. As the results, the strategy can improve the dynamic response speed of WGS as well as the yield of wind energy in steady and dynamic state. Analysis and simulation results confirm the validity of the strategy.
