This paper proposes an automatic load distributing algorithm called a general droop control for an inverter-interfaced islanded microgrid under different loading conditions and transmission line parameters. In this control scheme, both resistive and inductive nature of the transmission lines are considered. A linear model-based power sharing approach with the general droop controller is also described in this paper. The performance of the proposed controller is tested by simulating a simple two-source and one load-based microgrid test system and the simulation results show that the proposed method is useful to manage the load variation of an islanded microgrid accurately and efficiently.
