Abstract: Island areas are short of fresh water resources and the development of new energy desalination technology can ease the water stress problem of local residents by taking advantage of island' s rich wind energy and solar energy resources. This paper introduces the components, design, operation performance and cost analysis of new energy with independent power-grid and desalination system. The results obtained by operating the system in field show that the new energy system can meet the design requirements and the quality of fresh water, which is superior to the standard of drinking water. The system with its high lev el automation and strong ability for environment is suitable for solving the drinking problem in islands far from the mainland. The application of this project also can provide an important reference value for the development of off-grid desalination technology.

Key words: wind-solar-diesel complementary, independent power-grid, desalination
