| 摘 要： | 提出一种改进的风光互补发电系统最大功率跟踪的方法,由扰动观察法和二次插值法相结合,进行最大功率点跟踪。这种改进的方法结合了以上两种方法的优点,可以避免扰动观察法在最大功率点附近产生震荡现象,减小误判。并在MATLAB/Simulink上进行建模仿真,仿真结果表明,采用这种改进的控制方法,能快速地搜索到风光互补发电系统的最大功率点,并且稳定地工作。

| Abstract: | An improved maximum power point tracking method for wind-solar hybrid generation system was proposed in this paper. The maximum power point was tracked by Perturbation and Observation Algorithms and quadratic interpolation method. Taking the advantage of the above methods, the new method could avoid shock phenomenon of Perturbation and Observation Algorithms near the maximum power point, reduce miscarriage of justice. The whole system was simulated on MATLAB/Simulink. The simulation results shown that, the improved control method could search the maximum power point of wind-solar hybrid generation system quickly, and work stably. |
