Integrated protection scheme to coordinate MV distribution network devices, DG interface protections and micro-grids operation

The present work deals with the research of novel technical solutions to improve service continuity in MV distribution networks in presence of dispersed generation (DG). In particular, the paper focuses on the development of new criteria to manage both network protections and DG interface protections in a coordinated way, also in view of allowing portions of MV distribution networks to operate as intentional islands, in other words as temporary autonomous micro-grids, in case of faults or anomalies in the main distribution system.
