An Improved Incremental Conductance Algorithm for Enhancing the MPP of a Solar PV panel under various Atmospheric Conditions

Abstract

The control strategy ensures that the solar PV panel is always perpendicular to sunlight and simultaneously operated at its maximum power point (MPP) for continuously harvesting maximum power. The proposed control strategy is the control combination between the solar tracker (ST) and MPP that can greatly improve generated electricity from solar PV systems. Recording the ST system, the paper presents two drive approaches including open-loop and closed-loop drives. Additionally, the paper also proposes an improved incremental conductance algorithm for enhancing the speed of the MPP tracking of a solar PV panel under various atmospheric conditions as well as guaranteeing the operating point always moves toward the MPP using this proposed algorithm. The simulation and experimental results obtained validate the effectiveness of the proposal under various atmospheric conditions.
