Accurate Active and Reactive Power Sharing Based on a Modified Droop Control Method for Islanded Microgrids [PDF]
Sensors, 2023 When multiple paralleled distributed generation (DG) units operate in an islanded microgrid, accurate power sharing of each DG unit cannot be achieved with a conventional droop control strategy due to mismatched feeder impedance.

A finite-time reactive power sharing approach for microgrids
Energy Reports, 2020 Microgrid (MG) usually adopts droop control to stabilize its frequency and voltage. However, because the line impedance between distributed generators (DGs) is not proportional, the power sharing cannot be achieved.

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.

Accurate Reactive Power Sharing Strategy for Droop-Based Islanded AC Microgrids
IEEE Transactions on Industrial Electronics, 2023 In islanded AC microgrids, the mismatched impedances of the interfacing feeders between the inverters and the load bus cause poor reactive power-sharing when the conventional frequency and voltage droop control technique is employed. Such operation endangers the whole microgrid reliability as it may lead to overloading certain inverters and ...
