9 Lo sviluppo delle Fonti Rinnovabili Connessioni alla rete Enel (dati anno 2008) Consuntivi anno 2008 Rete BT Connessioni (n.): ~ Potenza media (kw/impianto): ~ 6,7 Potenza connessa totale (MW): ~ 154 Rete MT Connessioni (n.): ~424 Potenza media (MW/Impianto): ~ 1 Potenza connessa totale (MW): ~ 424 Rete AT Connessioni (n.): 23 Potenza media (MW/Impianto): ~ 35 Potenza connessa totale (MW): ~ 795 ~ MW di GD/FER connessi a rete Enel nel

13 Verso le reti di distribuzione attive Stato attuale Minimum Power on annual basis 40 Circa il 14% delle Cabine Primarie di Enel Distribuzione lavora già oggi in risalita (flusso energia da MT verso AT) Power [MW] N of HV/MV Substations 13

14 Verso le reti di distribuzione attive Profili giornalieri di carico dei trasformatori AT/MT POWER 0 POWER HOUR -800 HOUR POWER 0 POWER HOUR HOUR Il flusso di energia inverso si verifica con maggiori probabilità nelle ore notturne quando i consumi sono minori 14

16 Problemi di esercizio della Rete Sistemi di protezione La protezione delle linee di distribuzione radiale è progettata e coordinata per il flusso unidirezionale Il flusso bidirezionale in un feeder o parte di esso è un problema del tutto nuovo 16

17 Problemi di esercizio della Rete Gestione delle isole I Distributori sono responsabili di tensione e frequenza relativamente alle connessioni di tutti i clienti 17

18 Problemi di esercizio della Rete Gestione delle isole? Il funzionamento in isola non può essere consentito senza che tutti i clienti siano alimentati a tensione e frequenza entro i limiti contrattuali 18

20 Our perspective: the Smart Grid Uso: pubblico from a traditional passive grid with one direction power flow, centralized large power plants and control to a network with distributed generation and control and bidirectional power flow from electromechanical to a fully digital system Towards an internet like network where all the users can play an active role 20

21 Uso: pubblico Towards the Smart Grids Vision for the Networks of the future Multi-directional flows management Plug & Play technologies End user real time information and participation Seamless integration of new applications Central and distributed intelligence Central and distributed resources 29/05/2009 Public Lighting Rete di distribuzione e Smartgrids Smart equipments and power electronics 21

22 Context European Commission - Strategic Energy Technology plan targets by 2020: 20 % reduction of GHG emissions (when compared to 1990 levels) 20 % of renewable energy in the EU energy consumption (2005: EU 8.5 %; 2005: IT 5.2%, 17% in 2020) 20 % reduction of energy consumption (baseline 1990, 13 % compared to 2006) in compliance with the EU energy policy: reliability, sustainability, market efficiency 22

23 Smart Grids are high on the European energy agenda Electricity Grids is one of the six industrial initiatives proposed by the EU in the European Strategic Energy Technology Plan (SET-Plan) The Smart Grid European Technology Platform, has just concluded its work with a Strategic Deployment Document The EU ask for concrete proposals to set up a European Industrial Initiatives (EIIs) on Smart Grids. Several European Projects on going on Smart Grids related topics, e.g.: Address, Susplan, Fenix 23

24 Smart Grids European Industrial Initiative Public-Private partnership for the EU competitiveness Smart Grids European Technology Platform EU Strategic Energy Technology SET-Plan 7 EU Framework Program Other National Programs Vision Strategic Research Agenda Strategic Deployment Document Vision Goals Strategy Coordination European Commission European Industrial Initiative Private Funding - Financing Industry (DSO, TSO, ICT, TLC, Equipment supplier etc) Member States Concrete Proposals - Leadership National R&D Programs 24

25 The DSOs Initiative is an open platform Founding Members Uso: pubblico Finland Sweden United Kingdom Germany Poland France Czech Rep. Slovakia Hungary Romania Eon is joining the initiative Spain Italy Bulgaria Other DSOs will join The 6 founding DSOs represent more than 50% of the total European metering points 25

26 DSOs Initiative Objectives Uso: pubblico To define a concrete framework of a common research and demonstration program to foster the development of smart grids. To identify the medium and long term investments necessary to the development of a European integrated Smart Grid infrastructure To highlight shared action plans covering the main pillars of this development. 26

27 The expected benefits from the program 1. Improved peak consumption management 2. More efficient use of energy and further reduction of carbon emissions from the electricity industry. 3. Pave the way to the advent of electric vehicles 4. Start reducing the future investment and operational costs of the EU electricity distribution grids 5. Bring industrial benefits to European manufacturers by: Mitigating engineering and business deployment risks Converging towards European technology standards Validating the technology scalability and replication 27
