A data-driven droop control strategy for reactive power sharing and stability enhancement in islanded AC microgrids

International Journal of Electrical Power & Energy Systems
In islanded microgrids, distributed generation (DG) units employing conventional droop control often exhibit significant mismatches in reactive power sharing. This issue primarily arises from the mismatches in line impedances. These inaccuracies not only

Distributed Control of Islanded Meshed Microgrids

IEEE Access, 2023
The main objective in microgrids is keeping their frequency and voltage close to the rated values, and ensuring a precise power sharing of their distributed generators (DGs). This can be challenging in a meshed microgrid due to the tight coupling between
