AI Customer ServiceIn this situation, the DC bus voltage in the droop control zone is managed by two resources: the SC and battery, which improves the DC bus voltage regulation. Based on (2), this will reduce the step change in the storage current.
The DC bus voltage is detected in a DC nanogrid with droop control, and an outer voltage loop proportional (P) control, which corresponds to the droop action, generates a reference current to be established by the battery and the SC converters.
Then, when there is excess of energy, the auxiliary devices are connected to DC bus according to charging the requirements defined by the design voltage.
To meet the voltage levels shown in Section 2, the DC bus voltage in the MPPT area should be between 49.2 V and 45.6 V, with the solar converter injecting 4.1 A and 4.4 A, respectively.
Author to whom correspondence should be addressed. DC bus-voltage signaling (DBS) and droop control are often used in DC nano and microgrids with decentralized distributed energy resources (DERs). This technique effectively enforces the appropriate contributions of power sources and energy storage systems (ESSs) in steady-state situations.
On the other hand, when the DC bus voltage drops due to a load increase or a power shortage, the battery may suffer from a positive current, and the SC supplies a high-frequency component of the current.
