H2020 Osmose WP5: highlights & expectations

Agenda



In OSMOSE WP5, Terna is the leader of the Italian demonstrator (one of the 4 demonstrators of the project)

named “Multiple services provided by grid devices, large demand-response and RES generation coordinated in a

smart management system”.

Consortium Leader

Project Consortium (33 partners, RTE Coordinator):▪ 6 TSOs (RTE, REE, TERNA, ELES, ELIA, REN)

▪ 5 RES Producers (HSE, ENEL, E2i, Edison, Hydro Dolomiti)

▪ 6 manufacturers (ABB, Schneider Electric, EFACEC, SAFT, GPTECH,

INGETEAM)

▪ 2 ICT companies (IBM, Engineering)

▪ 11 research partners (CEA, EPFL, UPD, UDE, TU Berlin, RSE,

ENSIEL, ULPGC, CENER, R&D NESTER, FBK)

▪ 3 ESCO & consultants (Compendia, EKC, IT4Power)

Terna is part of the consortium of Horizon 2020 project OSMOSE, aiming at maximizing the RES penetration by

assessing the optimal mix of flexibility solutions to guarantee system security and adequacy.

Within the H2020 project OSMOSE, Terna is coordinating a demonstrator with the goal to assess the capability

of RES plants, grid devices and great industrial load to provide flexibility to the grid

DTR – Cooperative sensors

Energy Management System

A new EMS will be developed in order to manage different flexibility resources (innovative DTR, industrial DSR)

and test new grid services (e.g. synthetic inertia, frequency restoration reserve by loads)

1. Improve congestion management on HV (150 kv) grid and maximize RES production by coordinated use of innovative Dynamic Thermal Rating, other Power Flow Control devices, short-term forecasts and Demand Side Response resources

2. Provide Synthetic Inertia and Automatic Voltage Control (AVC) by large wind/solar power plants in coordination with traditional power plants

3. Support Frequency Restoration Reserve (FRR) and Automatic Voltage Control (AVC) by large consumers in coordination with traditional power plants

Aggregated demand sources RES Plant (also integated with Energy Storage)

Automatic Frequency Restoration Reserve: power

exchange with the grid based on a signal received by

the TSO, with the aim to restore nominal system

frequency

Congestion Management: modify generators/loads

production/consumption according to grid conditions

Automatic Voltage Control: increase or decrease the

reactive power exchange with the grid, helping voltage

regulation

Synthetic Inertia: power delivered as a function of

frequency deviation

Automatic Voltage Control: increase or decrease the

reactive power exchange with the grid, helping voltage

regulation

H2020 Osmose WP5Focus on innovative DTR architecture

An innovative DTR installation by means of Cooperative Sensors will be installed and tested in the demo area

▪ Dynamic Thermal Rating (DTR) of lines is an available technology where

the thermal rating of overhead lines is monitored in real-time. It aims at

giving a reliable and flexible tool to the operator to assess and then

maximise the transmission capacity while respecting the safety

margins (e.g. sag).

→Within OSMOSE, in order to address the problem of dynamic

loading of overheads lines a decentralized non-hierarchal

architecture based on cooperative dynamic agents has been

conceptualized, based on a proposal of ENSIEL

WP5 Demo Area and large consumer involvement

H2020 Osmose WP5

The demo area of WP5 demonstrator is a part of the grid between Apulia and Basilicata. The grid portion was chosen because of the high penetration

of renewable sources as well as a good number of large industrial consumers connected to HV.

FOCUS ANALYSIS: IDENTIFIED FLEXIBILITIES

In the 8 industrial plants analyzed the following flexibilities have

been found overall* :

❑ Congestion management

→ Up to 121.3 MW (27.3 loads, 94 generators)

❑ Frequency Restoration Reserve

→ Up to a 94.5 MW (500 kW loads, 94 generators)

❑ Automatic Voltage Control

→ Thousands of MVAr, of which 30 from loads

*Theorethical maximum values resulting from the analysis are shown.

For technical and budget reasons, only some of the flexibilities found will be tested

Flexibility analysis found out some interesting resources to be tested for electrical flexibility. These resource

will be properly aggregated in order to provide a significant result for the Grid
