摘要
提出一种复合的MPPT算法,即以恒定电压法启动的自适应变步长的增量电导法。恒定电压法用来迅速跟踪近似最大功率点,变步长导纳增量法则用来进行精确跟踪,并在Matlab/Simulink系统仿真模型中进行验证。实验结果证明改进的算法要比传统的固定步长算法优越。
This paper proposes a new combined adaptive MPPT algorithm, that is the improved Increment Conductance (INC) method with constant voltage( CVT), method startup and variable step-size. The CVT method is used to fast track the approximate maximum power point, while the improved INC is used for accurate tracking. The proposed method is tested in Matlab / Simu- link environment. The experimental results illustrate the advantages of the new algorithms in contrast with the traditional algo- rithms with fixed step-size.
