| 摘 要： | 在部分遮阴情况下，光伏阵列功率-电压(P-U)特性曲线呈现多个极值点，传统的最大功率点跟踪(maximum power point tracking，MPPT)方法会失效。提出了一种基于电导增量法的全局搜索（Global search based on Incremental conductance，GSINC）方法来实现最大功率点跟踪，该方法保证不会陷入局部最优且不会错过任何极值点。最后通过仿真验证了该算法能快速且准确的跟踪最大功率点，有效提高了光伏阵列输出效率。

| Abstract: | Conventional maximum power point tracking (MPPT) methods are ineffective under partially shaded conditions, because multiple local maximum can be exhibited on the power-voltage characteristic curve. A new control algorithm which was called global search based on incremental conductance (GSINC) was studied, the proposed algorithm will not fail into the local optimum and not miss any extreme points. Simulation results indicate that the proposed global MPPT algorithm can fast and accurately track the global maximum, and can improve the array output efficiency. |
