In-depth study on key technologies and energy management applicable to the microgrid can facilitate the maximum utilization of distributed energy and realize the intelligent

automatic and efficient energy exchange between the microgrid and the large power grid.In this paper

the networking topology

gridconnected/isolated network operation and energy scheduling of AC/DC hybrid microgridis studied and analyzed such strategies as load controlling

stabilization of new energy volatility

islanding operation

peak shifting and valley filling as well as load shifting and grid stitch on and off are proposed.The study result in this paper has been applied successfully to the microgrid pilot project which was constructed by a companyitself

which provides a platform for the study of grid-connected of distributed energy.
