传统电导增量法是太阳能光伏系统最大功率点追踪（MPPT）问题中应用最普遍的方法之一，但其存在着振荡和误判的问题，对太阳能系统的效率和稳定性有很大的影响。提出了一种新的MPPT算法：将功率预测法和电导增量法有机结合，同时应用变步长的理论来达到既减小振荡同时又克服误判的目的。与传统定步长电导增量法与变步长电导增量法相对比，在MATLAB 7中仿真的实验结果证明了该方法的可行性。

Traditional incremental conductance method is one of the most widely used methods of MPPT in solar photovoltaic system.But there are oscillation and misjudgment,great impact on the efficiency and stability of solar system.This thesis proposes a new MPPT algorithm,to combine power prediction method with incremental conductance method organically.Variable step theory is applied to reduce oscillation and avoid misjudgment. After the simulation in MATLAB7 ,it is proved to be feasible in comparson with traditional incremental conduct-ance and variable step INC.
