A critical review of Microgrid adaptive protection techniques with distributed generation

The main technical challenges in the emerging concept of the micro-grid (MG) and integration of sustainable energy resources in the Distribution System (DS) is the low fault current phenomena in the islanded mode of the MG operation and change in the network topologies with frequent DG connection and disconnection. The existing protection schemes require modification as they may fail to operate because of their inability to adapt to the changes...
