Proportional reactive power sharing for islanded microgrids [PDF]
2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA), 2016 In this paper, droop-based automatic control schemes are presented to control parallel inverter-interfaced distributed generators (DG) in a way that proportional reactive power sharing is possible in islanded microgrids under different structures. This paper modifies the conventional reactive power-voltage (Q-V) droop control strategy used in inductive

Enhanced Reactive Power Sharing and Voltage Restoration Based on Adaptive Virtual Impedance and Consensus Algorithm [PDF]
Energies, 2022 In this paper, power-sharing management control on an AC islanded microgrid is investigated to achieve accurate reactive power sharing. The droop control method is primarily used to manage the active and reactive power sharing among the DGs in the ...

Reactive power sharing in microgrid using virtual voltage [PDF]
International Journal of Electrical and Computer Engineering (IJECE), 2021 The traditional droop control strategy has been applied previously in microgrids (MGs) to share accurately the active power. However, in some cases the result obtained when sharing reactive power is not the best, because of the parameters related to the distances from distributed generators (DGs) to the loads and the power variations.

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.

Data-Driven Distributed Reactive Power Sharing in Microgrids [PDF]
2019 IEEE 58th Conference on Decision and Control (CDC), 2019 In this paper, reactive power sharing for Photovoltaic (PV) units in islanded microgrids has been formulated as a robust control design problem and is solved using convex optimization method. In addition to reactive power sharing, the disturbance rejection for voltage and active power have been formulated using infinity-norm constraints on the ...

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.

Optimized Reactive Power Control of Module Power Imbalance of Cascaded Converter
IEEE Open Journal of Power Electronics, 2022 In the medium voltage cascaded converter, the power imbalance problem among the converter modules will result in certain converter modules over-modulated. Reactive power control (RPC) scheme is an effective way to balance the cascaded converters.
