Analysis and implementation of virtual impedance for fixed‐frequency control strategy in microgrid
IET Generation, Transmission & Distribution, 2021 Classic droop control ensures the synchronization of distributed generation (DG) units inside a microgrid without requiring any deployment of communication links, however it causes unwanted frequency fluctuations and degrades system dynamics. Angle droop
