Optimized hill-climb search algorithm applied to directly driven wind-turbine with permanent-magnet synchronous generator
|
Abstract:
An optimized hill-climb search based on power-perturbation is brought forward for the direct-drive permanent-magnet wind-power generation(D-PMSG). This algorithm reduces the algorithm period and increases the speed in capturing the maximum wind power. By adding the function of data-store-access to the variable-step hill-climb search(HCS), we make this algorithm capable of generating the updated Max-Power work-table according to the motor speed for avoiding the repetitive calculations. Meanwhile, it realizes the tracking of the maximum wind power by integrating the power feedback control. Simulation results on MATLAB show that the proposed algorithm outperforms the traditional variable-step HCS in response speed and stability.
