Abstract
The objective of this work is the study, design and validation by simulation the model of an isolated photovoltaic chain composed of : PV Generator 4.2 KW, power conditioning system and a direct current load. This system is used to supply agricultural pumping station. The effects of temperature and irradiation on the PV Generator are studied, in particular on the magnitudes of the short circuit current, the open circuit voltage and the power delivered by the system. According to the characteristics of the load and the operating conditions (temperature, irradiation), we can find a big gap between maximum potential PV Generator power and that actually transferred to the pumping system. In order to extract in every moment the maximum of power available at the terminals of the PV Generator and transfer it at the pumping system, we use a matching stage composed of a boost converter controlled by an algorithm of power maximization "P&O" and a pulse width modulation (PWM).
TL;DRThe model of an isolated photovoltaic chain composed of PV Generator 4.2 KW, power conditioning system and a direct current load is studied, in particular on the magnitudes of the short circuit current, the open circuit voltage and the power delivered by the system. (Semantic Scholar)
