Can a voltage controller improve DC-bus voltage stability in DC microgrids?

Abstract: In this paper, a novel voltage controller of energy storage system (ESS) in DC microgrids (DC-MG) is proposed to enhance the DC-bus voltage stability. At first, a mathematical model of the DC-MG is developed in a state-space form.

What is DC bus-voltage signaling & droop control?

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.

How to control DC bus voltage in droop control zone?

In 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.

What is the DC bus voltage for a solar converter?

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.
