The popularity of low-voltage ac distribution networks is increasing day by day. However, an efficient protection scheme for low-voltage ac distribution systems is still challenging. This paper introduces a protection scheme suitable for low-voltage grid-connected and islanded ac microgrid based on local measurements in order to locate, identify and isolate faults. Here, a current decomposition method is specifically incorporated to accomplish fault type identification. The MATLAB/SIMULINK platform is chosen to examine the performance of the proposed scheme both in grid-connected and islanded low-voltage ac microgrid. The feasibility of the protection scheme is extensively investigated by simulating all types of faults with substantial variations, such as different fault locations and different fault resistances, among others. The test results ensure that the proposed protection scheme is sufficiently reliable and faster for providing complete protection in low-voltage ac microgrid.
