摘要: This paper presents a novel maximum power point tracking (MPPT) control method for variable-speed constant-frequency wind energy conversion systems (WECS). The proposed combines the ideas of sliding mode (SM) and extremum seeking (ESC). only input needed in this is output active generator. It avoids some difficult problems traditional algorithms, such as measuring velocity, needing wind-turbine model parameters, detecting gradient vs. rotor speed. tested on double fed induction generator based system. back-to-back converters connected to adopt vector method. simulation an example WECS established MATLAB. reference speed loop optimal result resulting from MPPT ESC. Simulation results confirm validity
