An improved INC-MPPT algorithm based on passivity approach for photovoltaic system

Abstract

International audienceNew robust algorithm of Maximum Power Point Tracking (MPPT) for an extraction system solar energy by photovoltaic effect is tackled in this paper. Indeed, the algorithms available today, suffer from non-robustness against climate change as well as system settings. This requires a deep study of the simulation of a robust controller system. Therefore, it is proposed, the Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) application for maximum power point tracking (MPPT), which shows its efficiency and robustness compared to other methods (such as Incremental Conduction), as fast and the decrease against climate perturbations and variationsof system parameters
