A droop control-based approach of effective power sharing among four parallel inverter-interfaced generators in an islanded microgrid has been proposed in this paper. Droop control strategy is applied during load change in islanded microgrid system in a way that power sharing among all the generators is also equal. This paper describes the small-signal stability analysis method to select the control gains needed to stabilize the considered microgrid system with desired power sharing among different generators connected in various buses. The real powers of distributed-generation (DG) units are shared based on the frequency, ...

The proposed power sharing scheme is verified with the help of MATLAB simulation.
