Research on grid connection technology of distributed power based on low-voltage AC/DC microgrid system

With the development of green low-carbon economy being strongly advocated, distributed power sources such as photovoltaic (PV) and energy storage (ES) have great potential in the construction of the new generation of power system. Based on the self-built low-voltage AC/DC hybrid microgrid system, the grid connection technology for single distributed power source and hybrid distributed power source including PV and ES is studied through simulation in this paper. At the same time, a grid -connected circuit is built to test the grid connection characteristics of PV and ES power supply, and the feasibility and operation stability of distributed power grid connection based on the system are verified, which provides support for largescale grid connection application of distributed power.
