6 FAQs about [Dc bus voltage control for a distributed power system]

How does DC bus voltage affect voltage-sensitive loads?

As a result, DC bus voltage suffers from rapid changes, oscillations, large excursions during load disturbances, and fluctuations in renewable energy output. These issues can greatly affect voltage-sensitive loads. This study proposes an integrated control method for the bus voltage of the DC microgrid to solve the abovementioned problems.

What happens if a DC bus voltage is greater than 2 volts?

When the oscillation amplitude of the bus voltage is detected to be greater than 2 V, the system activates the oscillation suppressor. Thereafter, the voltage compensator is activated at 2 s. The DC bus voltage with the conventional control method rapidly decreases to about 758 V, and the system inertia is insufficient.

What is DC bus voltage drift?

The DC bus voltage with the conventional control method rapidly decreases to about 758 V, and the system inertia is insufficient. Meanwhile, the busbar voltage drift is greater than 5%, which is beyond the safe operating range.

How fast does a DC bus voltage change?

The speed of the voltage change is fast, and the inertia of the system cannot be well represented. Under the integrated control strategy, the DC bus voltage change rate slows down significantly, the oscillation amplitude is reduced to about 2 V, and the bus voltage recovers to 800.5 V after the voltage compensator is operated.

What is the amplitude of a DC BUS oscillation?

After the method in is operated, the DC bus voltage is restored to 800.2 V. However, the amplitude of the oscillation is about 8 V. The speed of the voltage change is fast, and the inertia of the system cannot be well represented.

How does integrated control strategy affect DC bus voltage change rate?

Under the integrated control strategy, the DC bus voltage change rate slows down significantly, the oscillation amplitude is reduced to about 2 V, and the bus voltage recovers to 800.5 V after the voltage compensator is operated. Experimental waveforms comparing the method in with the proposed integrated control strategy
