Schema project-innovative criteria for management and operation of a closed ring MV network

In this paper is presented an innovative project that experiment, in a real MV distribution grid, a closed ring network operation by adopting an advanced control system that will be realized through: (1) use of sensors and fault detectors along the relevant points of the network; (2) use of circuit breakers instead of disconnectors in MV-LV substations; (3) a communication infrastructure based on optic fibres combined with MV overhead cables. In particular, in this paper are shown the main operating criteria and the technical solutions developed by Enel Distribuzione that will be applied to an existing network and also in the POI P4 project (closed ring MV network operation in order to increase network hosting capacity for the connections of new DGs). The project is being funded by the Italian Ministry of Economical Development, within an Innovation Program carried out in 4 Regions of the South of Italy in the frame of the Programma Operativo Interregionale (POI) “Energie Rinnovabili e Risparmio Energetico”.
