Considering the advantages of respective AC and DC microgrids
the output characteristics of distributed power supply and energy storage devices
and the power supply demand for load in China
this paper introduces the virtues of the AC-DC hybrid microgrid and its development in China
and analyzes its research status and development trend in the world.According to the load and power quality requirements of a science and technology tech industrial zone
an AC-DC hybrid microgrid technical scheme of high quality power supply for Chinese industrial zones is proposed.In addition
the key technologies and research direction of Chinese AC-DC hybrid microgrid are discussed on the basis of the existing research on microgrid technology.
