AVILA-PRATS, Deivis; ALESANCO-GARCIA, Ramón  e  VELIZ-ALONSO, Juan. Hybrid systems with base in the renewable energy for the energy supply to desalination plants. Ingeniería Mecánica [online]. 2011, vol.14, n.1, pp. 22-30. ISSN 1815-5944.

In the following work the hybrid systems with base in the renewable energy are modeled, to compare many different design options based on their technical and economic merits. The energy necessities will be guaranteed in reverse osmosis desalination plants, with a capacity of up to 50 m³ of daily production. The data processing was analyzed using the computer model, HOMER. The departure elements were: the electric demand of the desalination plant, the technical specifications of the equipments, as well as the potentials of solar radiation and the speeds of wind of the analyzed region (Canary Island). The conclusions show that the best hybrid system, from the technician-economic point of view for the energy supply to a reverse osmosis desalination plants with 50 m³/día of capacity, will be an (eolic-diesel) system, composed by: two wind generators, a batteries bank and a diesel generator. It is demonstrated that the wind speed is the determinant thermodynamic variable for the configuration of the analyzed hybrid systems, considering the existent natural energy potentials in the studied region.
