【摘要】 目前光伏电池的光电转换率较低,为有效利用光伏电池,需要对光伏发电系统进行最大功率跟踪。常规的跟踪算法在快速跟踪最大功率点的过程中存在精度低、适应性差和跟踪效率低等弱点,基于自适应思想,采用自适应变步长算法快速跟踪最大功率点,仿真结果证明该方法不仅增加了最大功率点跟踪的精度,而且提高了跟踪的速度与系统的稳定性。更多还原

【Abstract】 Currently,the photovoltaic conversion efficiency is very low.To improve the conversion efficiency of photovoltaic cells,the maximum power of photovoltaic should be tracked.However,the conventional tracking algorithms have many weaknesses in the process of fast tracking maximum power point: low precision,adaptability,and poor low efficiency.A new concept for MPPT was introduced,namely,the adaptive algorithm,which could not only quickly find the approximate point of maximum power,but also improve accuracy and speed.更多还原
