In ENTSO-E the TSOs cooperate regionally and on the European scale, and through ENTSO-E they communicate their needs and positions on European and regional issues • WEC - World Energy Council • WEC is the foremost global and inclusive forum for impartial dialogue and thought leadership on common energy future, including governments, industry and expert institutions. Its mission is to promote the sustainable supply and use of energy for the greatest benefit of all • VLPGO - Very Large Power Grid Operator • VLPGO is a voluntary initiative of the world’s largest Power Grid Operators, representing together more than 60% of the electricity demand in the world • OME - ObservatoireMéditerranéen de l'Energie • OME is the association of leading Mediterranean energy companies. The mission of OME is to promote the cooperation in the Mediterranean Basin, making of energy an element of regional integration

  6. Index • Terna profile and international organizations • CIM Standard in Terna and in ENTSO-E frame • Terna for smart grids

  7. CIM Standard in Terna and EuropeanTSOs • Old ASCII Standards permit only Load Flow Analysis and Three phase short-circuit • New CIM Standards allows performing also of unbalanced short circuit and dynamic analyses. Terna was convenor of Method & Tools in UCTE and actively fostered this process UCTE agreed to launch an initiative for development of new UCTE “XML based” data exchange format that will be considered as a standard for exchange of load flow and dynamic data November 2007: ENTSO-E System Development Committee decided for the first ENTSO-E data collection for planning models that will use CIM/XML Terna was convenor of Network Modeling & Data in ENTSO-E and supported this process September 2009: Actually ENTSO-E is collecting the first CIM Planning Grid Models: 2015 WP, 2015 SP, 2015 SoP and 2020 WP Terna provided CIM compliant models as well as DE, FR, AT, DK June 2010:

  8. CIM Standard in Terna and EuropeanTSOs Terna, as test witness, will attend the IOP test as well as attended IOP tests in Paris (2009) Next Inter-OPerability test in Brussels will involve the dynamic data exchange in planning and in operation July 2010: Next data collection for ENTSO-E operational models will test CIM standard; many TSOs are working in order to use CIM standard in operation Terna supports this activity as member of ENTSO-E Network Model & Forecast Tool Next step: Terna is convenor of System Adequacy & Market Model in ENTSO-E and will support this process Possible future data collection for ENTSO-E market models in CIM standard; Next step: In the next future it will be useful thinking about the full use of the CIM/XML standards for TSO’s internal data exchange.

  9. Main data handled in TERNA SPIRA Planning Tool Main internal data exchange could be done by CIM/XML format SICRE Dynamics Tool CRESO OperatingTool SCADA PROMED Market study Data Exchange with other Parthies (e.g. ENTSO-E, TSOs) Statistical database Registry database GIS database

  10. Index • Terna profile and international organizations • CIM Standard in Terna and in ENTSO-E frame • Terna for smart grids

  11. Smart Grid concept SGs are innovative electrical grids that allow the integration of the Centralized and Distributed Generation. By the future configuration of the network (microgrids or virtual power plants), the unit connected of the grid could be controlled to ensure the full exploitation of the resources on the grid. • Goals of the integrated network: • Ensure the transmission grid reliability • Improve the grid exploitation • Increase the operating flexibility • Simplify the grid access • Raise the efficiency of the power system

  12. Smart component on the Italian Transmission System Installed at the moment • PSTs system on the 380 kV Albertville-Rondissone double line • Nominal Power = 2x1.630 MVA • In service since 2004 • It controls the power exchange from FR to IT and balances flows on FR-IT tie-lines • It adjusts the power exchange, balancing it between France and Switzerland to Italy • PST on the 220 kV Padriciano-Divacca • Nominal Power = 370 MVA • In service since 2007 • It controls the power exchanges form SL to IT • It balances flows on the 400 kV Divacca-Redipuglia and 220 kV Divacca-Padriciano tie-lines • HVDC SA.PE.I (Sardinia – Mainland) • Power capacity = 2x500 MW (in service since 2009 the first 500 MW pole) • It controls the transferred power from/to Sardinia and improves the Security of Supply • Automatic Trip Devices - WAMS • Increase the exchange among market zones • Improve the grid exploitation

  13. Smart component on the Italian Transmission System Installed at the moment: how the Albertville-Rondissone PSTs system works? Scenario A: PSTs managed disjointed Scenario B: PSTs balance flows on the FR-IT tie-lines Scenario C: PSTs control flows from FR to IT in case of the 380 kV Venaus-Villarodin is unavailable ABVZ (FR) RONT (IT)

  14. Smart component on the Italian Transmission System Installed at the moment: how the Albertville-Rondissone PSTs system works? Scenario A.0: PSTs managed disjointed Scenario A.1:N-2 Robbia-Sfiorano/Robbia-Gorlago contingency -> Import from FR to IT increases Scenario A.2: after the contingency, PSTs system control flows thus balancing the import on the North border ABVZ (FR) RONT (IT)

  15. Smart component on the Italian Transmission System Installed at the moment: how the Padriciano PST works? DIVL (SL) Scenario A,B.0: PST balances flows among the IT-SL tie-lines Scenario B.1:N-1 Divacca-Redipuglia contingency -> Increases the import on the 220 kV link controlled by the PST Scenario B.2: after the contingency, PST adjusts flow on the 220 kV link thus reducing the import from SL to IT PDRV (IT) RDPV (IT)

  16. Smart component on the Italian Transmission System Installed at the moment: how the Automatic Trip Devices work? ATD system increases the exchange capacity among market zones It improves also the grid exploitation and the energy production by more efficient power plants

  17. Smart component on the Italian Transmission System Planned: ahead full SGs implementation into the Italian Transmission System • Sometime power flows on the grid are undesirable • FACTSs allow to control and modify the parameters in the grid thus obtaining the redispatching of power flows • PST device controls the voltage phase angle among two node changing the transferred active power • HVDC device allow to change the transferred power among poles Smart system involves PST, HVDC, … PST 6 HVDC 4 5 3 400 kV link 2 220 kV link 1 8 7

  18. Smart component on the Italian Transmission System Planned: ahead full SGs implementation into the Italian Transmission System Capacitors and reactors allow to control the reactive power on the grid thus obtaining a voltage/var optimization (> 3.000 MVAr) Capacitors on the HV network Reactors on the EHV network Studies show that the grid needs a var regulation system (SVC, STATCOM,…) to regulate the reactive power in the network thus improving the voltage profile also in dynamic conditions. Implementation studies of smart components on the grid require an exchange of a huge quantity of information about the network CIM code

  19. Back-up
