Optimization of Renewable Power System for Small Scale Seawater Reverse Osmosis Desalination Unit in Mrair-Gabis Village, Libya

摘要

Potential of renewable power system for small scale seawater reverse osmosis desalination unit in Mrair-Gabis village, Libya is evaluated. HOMER optimization model is used to evaluate the different possible configuration options for supplying the electrical load. This includes sizing, simulation and economic estimation of the system based on 0.25$, 0.5$ and 0.75$ diesel prices. At 0.25$ diesel price, the Gen/Battery option is the best economically. At 0.5$ and 0.75$ diesel prices, solar energy takes a good share when solar radiation intensity is more than 6.7 kWh/m~2 and 4.6kWh/m~2 respectively and the PV/Gen/Battery combination becomes more feasible. Wind energy on the other hand does not seem to be cost effective in the sensitivity analysis because the wind potential is limited at the particular site of study.
