To enhance the stability of the microgrid after the energy storage system is connected, the DAB energy storage system needs to use a DC droop control strategy to compensate for power shortages in off-grid conditions. The I-U curve of droop control is shown in Figure 5.
What happens if a power supply goes off-grid?
There is a slight fluctuation in output power when the system goes off-grid, but it returns to normal after 0.15 s, and the bus voltage magnitude remains essentially unchanged. As the power deficit increases to 25 kW, the amplitude of the output power increases, the number of oscillations rises, and the recovery time extends to 0.22 s.
What happens to a microgrid during off-grid switching?
Particularly during off-grid transitions, the microgrid loses the stability provided by the main grid, and the microgrid itself must minimize power deficits that occur instantaneously during off-grid switching.
