Distributed Maximum Power Point Tracking for Mismatched Modules of Photovoltaic Array

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

The multiple peaks in the output P-V characteristics of the photovoltaic (PV) module and the complete loss of shaded module’s generation due to the existing bypass diode-based scheme are eliminated through the implementation of proven distributed maximum power point tracking (DMPPT). Considering the unique behavior of each PV Module, the artificial neural network is used in the DMPPT
algorithm to track the MPP at every instant by learning the unique behavior of each PV module in this chapter. This eliminates the effect of manufacturing dispersion. Though the unique MPP is identified, the inability of the DMPPT algorithm in maintaining the PV modules in its own MPP is eliminated by the compensator circuits which are introduced in the array configuration along with the DMPPT in this chapter. These compensators enabled the maintenance of each PV module in its own MPP by providing the deficient current of each module and the deficient voltage of each string. So, this configuration increases the output power by including the generation of shaded modules instead of bypassing it. The results show that the proposed configuration avoids the multiple peak condition in P-V characteristics and improves the efficiency of the PV array under partially shaded conditions.
