Protection Schemes for Meshed Distribution Systems with High Penetration of Distributed Generation
Paper i proceeding, 2006

This paper identifies the impact of high DG penetration on protection coordination and proposes a protection scheme to mitigate the identified problems, in a network with high penetration of DG. The scheme emphasizes on keeping most DGs on line to supply loads during the fault, without putting DG or any part of the distribution network in islanding operation, whilst ensuring that the conventional overcurrent protection devices (breakers with overcurrent relays – reclosers – fuses) do not lose their functions and their proper coordination.
