This paper focuses on an intelligent MPPT (maximum power point tracking) algorithm for permanent magnet vertical-axis direct-drive wind turbine systems. The relationship between generator speed and buck convert’s duty ratio is analyzed. then, the output and the speed of wind turbine are controlled by convert’s duty ratio. In this way an intelligent MPPT algorithm, the different step length is given in different directions, is used to this system. At last, the system is simulated by software, and the simulation results indicates that compared with the conventional MPPT strategy, the rapidity and the stability are increased by intelligent MPPT algorithm.
