Strategic Target forward Sustainable Growth and Key Development Projects

• The New Strategic Plan includes total investments for over 4.3 bn€ (3.3 bn€ of which for grid development).

November 2007:

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

Old ASCII Standards permit only Load Flow Analysis and Three phase short-circuit

CIM Standard in Terna and European TSOs

Terna was convenor of Method & Tools in UCTE and actively

fostered this process

New CIM Standards allows performing also of unbalanced short circuit and dynamic analyses.

September 2009: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

June 2010: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



July 2010: Next Inter-OPerability test in Brussels will involve the dynamic data exchange in

planning and in operation

CIM Standard in Terna and European TSOs

Possible future data collection for ENTSO-E market models in CIM standard;

Terna, as test witness, will attend the IOP test as well as attended IOP

tests in Paris (2009)

Terna is convenor of System Adequacy &

Market Model in ENTSO-E and will

support this process

In the next future it will be useful thinking about the full use of the CIM/XML standards for TSO’s internal data exchange.

Next step:

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:

Data Exchange with other Parthies

(e.g. ENTSO-E,

TSOs)

Main internal data exchange could be done by CIM/XML

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.

Smart Grid concept

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



Smart component on the Italian Transmission SystemInstalled 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

Reactors on the EHV network

Capacitors on the HV network


Capacitors and reactors allow to control the reactive power on the grid thus obtaining a voltage/var optimization(> 3.000 MVAr)

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
