When the solar-storage DC microgrid operates in islanded mode, the battery needs to stabilize the bus voltage and keep the state of charge (SOC) balanced in order to extend the service life of the battery and the islanded operation time. When there are multiple energy storage units in the DC microgrid, it is necessary to solve the problem of unbalanced

This paper considers a new droop control per phase of a four-wire microgrid to solve the problems associated to unbalanced operation (e.g. high neutral current). Unlike the conventional approaches, in this work, the active power per phase of each converter is shared varying the output voltage angle of each inverter phase.
Ideally, all units should share the load uniformly, and from (), it is clear that it is possible only when voltages V 1, V 2 and resistances R 1, R 2 are equal as ΔI becomes zero in that case.But conventional droop control is only a compromise between voltage regulation and current sharing as there is always some variation in cable resistances or some other
Abstract: Droop control is a technique used in microgrids to manage active power without internal communication. As a result, it lowers the complexity and expense of running the system and raises reliability metrics.

Abstract: When a microgrid is extended by shunt converters, the deviation between its line impedances can lead to active/reactive power coupling, which affects the sag control performance and effectiveness and increases system power losses.

The droop control strategy is one of the best strategies which has its own advantages and disadvantages. Droop control is the best-accepted strategy for controlling parallel multiple inverters working under the autonomous mode . Droop-based control has many advantages such as great flexibility, high reliability, and no communication needed.
The most common type of droop control is conventional droop control. In conventional droop control, frequency and voltage vary linearly with respect to active and reactive power, respectively. For instance, assigning a 1% frequency droop to a converter means that its frequency deviates 0.01 per unit (pu) in response to a 1.0 pu change in active

The droop resistance is dynamically adjusted for each unit within the microgrid via current sharing loops in adaptive control, necessitating low-bandwidth communication networks for sharing unit currents among droop controllers. Traditional PI controllers are utilized to fine-tune the droop parameters.
The current droop control methods used in DC microgrids suffer from significant drawbacks, such as poor voltage regulation, the use of fixed droop values regardless of the instantaneous voltage deviation, and unequal load sharing.
