Modeling and Simulation of Multipumping Photovoltaic Irrigation Systems

The growing market of large-power photovoltaic irrigation systems (PVISs)—made with different and several motor pumps working in parallel—needs simulation tools capable to estimate their energy water productivity. objective this paper is present the models developed for parallel multipump PVISs fed by a single PV generator. These seek maximize instantaneous flow rate according available power were typical configurations facilities. some advantages when compared current state art (in which pump connected 1/N fraction generator simulated result multiplied N): case negligible hydraulic friction losses, use model shows gains respect art; appreciable overestimates productivity systems. Then, ability these compare designs shown: two groups at variable frequencies show better performance than group frequency nominal frequency—an 8% increase pumped seen.
