Abstract:
In recent years, the amount of new energy power generation has gradually increased, and the DC power grid has become more widely used. In order to ensure the stable operation of the DC grid, the voltage control strategy has received extensive attention. Based on traditional droop control, this paper considers the balance of state of charge（SOC） between virtual inertia and energy storage units, and innovatively proposes virtual inertia control considering SOC equalization. By adding a correction factor, the droop coefficient is continuously changed to maintain the voltage stability of the DC grid.
