In this article, a new impedance-based scheme for microgrid protection in grid-connected and islanded modes is proposed. . Aiming at the problems existing in micro-grid, a set of protection schemes, which are according to the fault characteristics of micro-grid system with different voltage levels of 10kV and 400V in distribution network, are proposed in this paper. According to the simulation results, it is verified. . Microgrid properties including bidirectional power flow in feeders, fault level decrease in the islanded mode, and intermittent nature of distributed generators (DGs) result in the malfunctioning of microgrid conventional protection schemes. However, incorrect. . Abstract—AC Microgrids, in presence of highly non-linear loads, require a tighter regulation of line voltage to maintain power quality. This work made use of shared facilities sponsored by ERC program of the National Science Foundation (NSF) and DOE under NSF award number EEC-1041877 and the CURENT Industry Partnership Program.
