Abstract

Under partially shaded conditions (PSCs), multiple peaks appear on the power-voltage curve of the photovoltaic (PV) array, which makes it difficult to track the global maximum power point. To address this issue, we first analyze the nonlinear characteristic of PV array under PSCs. On this basis, a novel global maximum power point tracking scheme is proposed, which consists of two major subroutines: genetic algorithm (GA) and 5-dot perturbation and observation (P&O) method. The GA subroutine is used to shift the operation point to the vicinity of the global peak, and 5-dot P&O subroutine is used for accurate tracking. The validity of the proposed scheme is verified by experimental results.
