Battery-Supercapacitor Hybrid Energy Storage Systems for Stand-Alone Photovoltaic

Abstract

In this paper, we proposed, modelled, and then simulated a standalone photovoltaic system with storage composed of conventional batteries and a Supercapacitor was added to the storage unit in order to create hybrid storage sources (batteries and Supercapacitor), and to better relieve the batteries during peak power. And reduce stress on the batteries by avoiding deep discharges. This study includes, on the one hand, a MPPT (Maximum Power Point Tracking) algorithm integrated to the control of this converter allowing the photovoltaic panels to operate according to their optimal nominal voltage, thus providing the maximum power. On the other hand, efficient global management allows the system to offer optimal performance.
