An irrigation scheduling algorithm for sustainable energy consumption in pressurised irrigation networks supplied by photovoltaic modules

Abstract To meet water demands, pressurised irrigation networks often need pumping devices, whose power demand varies with the pump head, flow rate delivered and efficiency. satisfy energy of pumps, solar photovoltaic panels can be used as a renewable source. Since electricity supply photovoltaics plant depends on irradiance, that powers time day. This study presents strategy for scheduling delivery by synchronising production in modules minimising installation size. An optimisation algorithm is proposed, which changes required devices adjusts them to available supply, number required. problem applies network, where utility manager may irrigate crops at all hours By adopting proposed algorithm, will follow rigid rotation schedule new plan. approach improves earlier studies employing least-square little computing time. results tool managers decision-makers when evaluating possibility converting their network into stand-alone system supplied panels. A case handling this issue University Alicante’s Spain find potential savings connecting recommended irrigating plan present operation. Graphical abstract
