Abstract

Due to differences in insolation levels caused by shading and different inclination angles, the Photo-Voltaic (PV) panels in the same array could have different power-voltage characteristics. This effect creates a number of peaks in the power-voltage characteristics of the entire array. Conventional Maximus Power Point Tracking (MPPT) techniques could therefore get trapped in a local maximum rather than tracking the global one. In this paper, a novel Global MPPT (GMPPT) algorithm is proposed to address the discrepancy in PV panels' outputs. First, the model of PV array with different insolation levels is built to analyze the output characteristics. Second, a GMPPT algorithm is proposed to track the global maximum power point. Finally, simulations in different insolation scenarios are performed to demonstrate the effectiveness and superiority of the proposed algorithm.
