摘要
电力供应的滞后制约了海岛及其周边海域的开发。海水抽水蓄能技术以海洋作为低位水库,降低工程建设成本,可解决传统抽水蓄能技术对淡水资源过度依赖和环境破坏等问题。研究表明,海水抽水蓄能与风能、太阳能、海洋能等可再生能源组成联合发电系统具有可行性,能够实现海岛可再生能源的大规模开发和利用。介绍了海岛供电系统的现状,阐述了海水抽水蓄能技术的工作原理和应用现状,分析了技术应用中存在的问题和挑战,并对海水抽水蓄能技术在海岛供电系统中的应用前景作了展望。
The lag of power supply restricts the development of the island and its surrounding waters. The seawater pumped storage technology takes the ocean as the low-level reservoir and reduces the construction cost, which can solve the problems such as over-reliance on freshwater resources and environmental damage by traditional pump-storage technology. Research shows that it is feasible to combine the water pumped storage with the renewable energy resources, such as wind power, solar energy, and oceanic energy, into power generation system, achieving the large-scale development and utilization of renewable energy on the island. This paper introduces the present situation of the island power supply system, expounds the working principle and present application of water pumped storage technology, analyzes the problems and challenges existing in the technical application, and suggests the prospect of the water pumped storage technology application in the island power supply system.
