Coordination of Overcurrent, Directional and Differential Relays for the Protection of Microgrid System

Procedia Technology, 2013
AbstractMicrogrid implementation draws new challenges especially in the coordination of protective devices that are not likely to appear in a traditional distribution network. Variation of fault current levels, bi-directional fault current and changing of microgrid operation modes make protection of the microgrids more difficult.
