Review on sustainable development of island microgrid

In microgrid, distributed generators (DG) can be utilized effectively, and controlled intelligently and flexibly. By use of rich renewable energy sources (RES) on islands, island microgrids can be built to develop clean and pollution-free renewable energy power industry, which makes islands´ natural balance of the regional energy industry achieved, the `renewable energy´ economy developed, the industrial structure optimized, and industrial systems with circular economy established. RES on islands of China, including wind, solar, biomass, ocean current energy, wave energy, tidal energy, ocean thermal energy, ocean salinity gradient energy and geothermal energy, are summarized in this paper. It was carried out that comparison among international definitions and structures of microgrid currently, together with that analysis on features of an island microgrid. The domestic and international research was reviewed on island microgrid based on renewable energy power generation. A comprehensive overview of some projects was presented. Finally, it was pointed out that some key issues, which should be paid attention to during the island microgrid developing progress. All of these are of great referential and guiding in island microgrid development.
