Abstract:A MPPT(Maximum Power Point Tracking)control method of PV(Photo Voltaic)generation system is proposed,which applies CV(Constant Voltage)method to adjust the working point of PV array near the MPP(Maximum Power Point)for fast tracking when external conditions or loads change suddenly,and uses CI(Conductance Increment)method with small-step to optimize the steady state characteristic of MPP for effective reducing the output power oscillation around MPP. The CV, CI and proposed methods are simulated respectively and results show that, the proposed method tracks the MPP exactly and quickly and improves the energy conversion efficiency of PV generation system by reducing the output power oscillation around MPP.
Keywords:photovoltaic array  photovoltaic generation system  MPPT  constant voltage method  conductance increment method
