Reactive Power Synchronization Method for Voltage-Sourced Converters [PDF]
IEEE Transactions on Sustainable Energy, 2019 There is a growing interest in the parallel operation of voltage source converters (VSCs) both in an isolated microgrid or connected to the utility grid. The most common solution in the literature for the paralellization of VSCs is the so-called droop control, which brings about a relationship between active power and frequency.
