摘要
淡水资源和常规能源短缺是限制海岛开发和海洋经济发展的主要因素。新能源海水淡化具有环境友好、供水保障率高、经济合理等优点,逐渐成为离岸中小岛屿供水保障研究的热点。文章在充分调查分析海岛新能源资源及其发电输出功率特点和海水淡化装置对电能质量要求的基础上,设计了新型独立微网能源管理策略,形成了成套的风光互补式微网海水淡化技术,并进行了工程应用。结果表明,风光互补式微网海水淡化系统运行稳定,对环境的适应能力强,适于解决岛屿的饮用水问题。在风、光等可再生能源资源较丰富、海水资源良好的海岛,风光互补式海水淡化系统的综合制水成本约为10元/m3,相对于大陆引水、船舶运水等其他岛内淡水供应方式具有明显的经济和生态环境优势,具有较为广阔的推广应用前景。
The shortage of fresh water and conventional energy is major factor restricting the development of the island and the marine economy. Seawater desalination powered by renewable energy has the advantages of environment friendly, high water supply reliability and economic rationality, and gradually becomes the research focus in the field of small offshore island water supply. Based on the full investigation and analysis of the space distribution and complementary characteristics in time of renewable energy resources in island, power output characteristics of renewable energy generation and requirements of seawater desalination device on electric energy quality, a novel isolated micro-grid energy management strategy is presented in this paper, a set of technology for seawater desalination powered by wind and solar hybrid micro-grid(abbreviation as SWWSMG) is created, which has been applied to a demonstration project. The results show that the SWWSMG has some advantages such as stable operation, strong ability to adapt to the external environment and suitable application in drinking water in the island far away from the mainland.For offshore islands with abundant renewable energy resources, such as wind energy, solar energy and so on, and clean seawater resources, the specific production water cost with the technology of SWWSMG is close to 10 $/m3, and it has obvious economic advantages and ecological advantages compared with other ways such as shipping and pumping from mainland, it has a good application prospect.
