A good microstructure, especially in autonomous mode, requires a power management strategy. In an island microgrid, there are two methods of centralized and decentralized control. In an island microgrid, the slope changes characteristic of the frequency droop of the source frequency have the greatest effect on the dynamics of the system's response to disturbances in the microgrid. In this paper, the inverter-based microgrid droop control method in island operation mode is analyzed and simulated. The studied system has three scattered sources and six local times. The simulation results are shown using MATLAB software for different modes.
