چکیده
The idea of hydrogen production by water electrolysis from renewable sources is one of the most obvious methods. It could not only lead to a significant reduction in greenhouse gas emissions, but also to increase the security of energy supply due to the method of clean storage. In this paper, we have borrowed a new method for hydrogen production by adapting the electrolysis to a photovoltaic (PV) source, in order to produce the maximum of hydrogen. The electrolysis is considered as well as an electrical load connected to the photovoltaic system via a DC/DC buck converter, having a system control tracking of maximum power point MPPT P&O, which allows the maximization and control of the power transferred to the electrolysis. Furthermore, this study shows that the maximum hydrogen production is not related to the quantity of water to be electrolyzed, but the need to control the water flow which enters electrolysis according to variations of the power arising from weather changes. The overall results show that for constant power, water flows are simulated by injecting constant resistive loads.
