Abstract:In a grid-connected photovoltaic power system, it is vital to have the maximum power point tracking to improve the efficiency of photovoltaic power system. This article introduces views about power loss into the analysis of maximum power point tracking, discussing in detail the power loss due to the misjudgment during the oscillating and tracking of perturbation and observation method. A revised perturbation and observation method is proposed and by experiments it is proved that it can solve well problems of oscillation, tracking resolution and speed.
