Secondary control for reactive power sharing in droop-controlled islanded microgrids [PDF]
2012 IEEE International Symposium on Industrial Electronics, 2012 This paper focuses on the islanded operation of microgrids. In this mode of operation, the microsources are required to cooperate autonomously to regulate the local grid voltage and frequency. Droop control is typically used to achieve this autonomous voltage and frequency regulation. However, droop control has real and reactive power sharing

Distributed secondary controller to ensure proportional sharing of reactive power in AC microgrid [PDF]
Energy Reports, 2022 In an ac microgrid, reactive power sharing accuracy is affected due to unequal values of interconnecting cable impedances. To resolve this issue, secondary controllers are used to compensate the effect of cable impedances.

A consensus-based distributed voltage control for reactive power sharing in microgrids [PDF]
2014 European Control Conference (ECC), 2014 We propose a consensus-based distributed voltage control (DVC), which solves the problem of reactive power sharing in autonomous meshed inverter-based microgrids with inductive power lines. Opposed to other control strategies available thus far, the DVC does guarantee reactive power sharing in steady-state while only requiring distributed communication

A novel partial transient active-reactive power coupling method for reactive power sharing
International Journal of Electrical Power and Energy Systems, 2019 Abstract In this paper, a control strategy has been presented to improve the reactive power sharing among distributed generation units in the islanded microgrids. The proposed control method is based on exerting a partial transient coupling between active and reactive powers.

Grid Agnostic Droop Control Strategy for Damping Restoration and Optimal Reactive Power-Sharing
IEEE Open Journal of Power ElectronicsIn low-voltage microgrids, parallel grid-forming inverters face the challenge of disproportional reactive power sharing due to (i) the local nature of voltages and (ii) the cross-coupling between the frequency and voltage droop control loops resulting ...
