摘要：

A new method which can linearize the nonlinear internal impedance was proposed. Based on the concept of dynamic equivalent impedance error, the engineering significance of dynamic equivalent impedance matching and the validity of dynamic equivalent impedance error control method were discussed. According to the thought of equivalent impedance matching, the self-optimizing maximum power point tracking (MPPT) control structure and algorithm in the photovoltaic power generation were developed, which can be achieved by digital. The experimental results show that the dynamic equivalent impedance matching algorithm has more obvious advantages, compared with the classic MPPT control algorithms. © 2011 Chinese Society for Electrical Engineering.
