摘要
针对以往光伏发电系统太阳能最大功率点跟踪（Maximun Power Point Tracking，MPPT）算法的跟踪速度及精确度不理想的特点，提出了一种新颖的变步长滞环比较法，对传统扰动观测法存在的速度和精度的矛盾进行优化。在Matlab／Similink下进行系统的建模与仿真，并进行实验分析。结果表明，该方法能够显著提高MPPT跟踪的速度和精度。
For the unsatisfactory tracking speed and accuracy of the maximum power point tracking （MPPT） algorithm for solar photovoltaic power generation systems in the past, a novel variable step hysteresis method is proposed to optimize the contradiction of the speed and precision of the existing traditional methods. Modeling, simulation and analysis are done through Matlab/Similink. The results show that the method can significantly improve the speed and precision of MPPT tracking.
