【 摘 要 】

The demand for power supply system is getting higher and higher in the development of modern society. Due to the rise of renewable energy, a large number of distributed generation units will be incorporated into the power grid, which has a negative impact on the safe operation of the power grid. Micro grid technology eliminates this effect, and DC micro grid is more suitable for distributed power access. Based on the research of DC micro grid droop control and voltage recovery control strategy, we use energy stratification method to control the operation of microgrid. It also points out the importance of the battery group in the operation process of the DC microgrid network. Finally, the effectiveness of the control strategy is verified by simulation.
