A load shedding scheme for inverter based microgrids

[摘要] Over the last decade, penetration of microgrids containing distributed generation (DG) sources has increased in grid distribution systems. This requires the stable operation of microgrids when connected to the distribution system as well as during islanding. Islanding that is fault provoked is more likely to cause unstable microgrid operation than planned islanding. During fault provoked islanding, unstable operation is exacerbated when induction motor (IM) loads are present. Using the MATLAB simulation tool SimPowerSystems, an inverter-based microgrid model connected to the IEEE-13 distribution system was created. A load shedding scheme was developed in order to improve microgrid stability during fault provoked islanding conditions.
