Sizing of the Sustainable Irrigation System Driven by Solar Photovoltaic Energy and Wind by Using New Sizing Algorithm

Using of renewable energy sources in irrigation systems nowadays is very important, due to reducing the use of fossil fuels and due to negative effects of climate changes. This paper presents a new sizing methodology for an irrigation system driven by solar photovoltaic (PV) energy and wind energy with regards to critical period(s). This kind of methodology hasn’t been presented so far. The analyzed irrigation system consists of four subsystems: subsystem PV (photovoltaic subsystem), subsystem W (wind system), subsystem R (water reservoir) and subsystem P (pump station). For each subsystem, critical period(s) will be defined: tPV*, tW*, tR* and tP*. Also, this paper will present two possible combinations for powering the irrigation system. In the first one, PV energy is the main source of energy and the Wind system is a backup, while in the second variant the Wind energy is the main source and the PV system is a backup.
