| 摘 要： | 对光伏发电系统提出了一种新的最大功率点跟踪（MPPT）控制方法，即在外界环境或负载突变时，先采用固定电压法将光伏阵列的工作点调整到最大功率点附近，以保证跟踪的快速性；在此基础上引入小步长的电导增量法，对最大功率点处的稳态特性进行优化，可有效减小光伏阵列的输出功率在最大功率点的振荡现象。

| Abstract: | A maximum power point tracking （MPPT） control method of photovoltaic （PV） generation system is proposed, which applies Constant Voltage Method to adjust the working point of PV array near the maximum power point （MPP） for fast tracking when external conditions or loads change suddenly, and uses Conductance Increment Method with small steps to optimize the the output power oscillation around MPE steady state characteristic of MPP and thus effectively reduce |
