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.
