HV/MV Substation Ginosa - Puglia MW The substation is equivalent to a Virtual Power Plant fuelled by renewable DG (e.g. clouds effect on DG output) August, 30 th 2010 August, 29 th 2011 August, 27 th 2012 hour DG dispatching will be key to address future challenges through Smart Grids technologies 25

26 How to deal with this, without jeopardizing system s security Monitoring enhanced remote control capabilities automatic optimal network configuration real-time data exchange with TSO Forecasting renewable DG modelling weather data mining generation output prediction algorithms Dispatching real-time telecommunication and DG coordinated control predictable profile of HV/MV Substation s load demand response 26

27 To validate SG technologies Enel has launched a complete set of projects in Italy

28 Summary Grid Resilience excellence requires an Integrated approach Network planning oriented improve structural resilience Operational resilience and crisis management to ensure quick and focused response Towards an active distribution network to manage effectively high penetration of renewable and distributed energy resources 28
