回顾了微网技术发展历程及研究现状，分析了微网特点，并从海岛能源需求出发探讨了海岛微电网建设的一些关键技术问题，提出了偏远海岛微网建设指导思想和适合当前国情的海岛微网技术路线、以及研发适合微网设计软件工具和积极开发海岛微网适宜产品的设想。

The development process and research status of micro grid are reviewed, and its characteristics are analyzed in this paper. Furthermore, some key technologies of micro grid construction in island are discussed based on the energy demand in islands. Finally, the guiding ideology of micro grid construction in remote islands, and the technological route of micro grid in islands which would be adapted to the practice situation of China are suggested, as well as the software for the design of micro grid and some suitable products are developed.
