Smart Grids, a new Paradigm for Territories
DETAILS
Thursday October 18th of November 2012
Reporters: Gabriel Bermeo and François Apicella
1st Speaker: Marie-Françoise GUYONNAUD - FONDATERRA
The European Strategy regarding the decarbonisation focused on the 3 main points:
1) reduction by 80% of the CO2 emissions by 2050
2) deployment of renewable energy by 2050 (55% of total energy)
3) reduction of non-renewable energy of 40% by 2050 (45% of total energy)
In the timeframe of European strategy, the SMART GRIDS (SG) will be essential in order to:
- balance the couple offer / demand
- distribute the renewable intermittent energy
- manage peaks of demands and allows more flexibility
- manage security aspects
- develop new markets (mobility,...)
Despite the necessity and urgency of the situation, things evolve too slowly.
2d Speaker: Carlos MORENO - COFELY - INEO - GDF SUEZ
GDF SUEZ invests in R&D for the SMART GRIDS and evaluates the following:
- what is the economic model for the SG ?
- what are the markets for the SG ?
- what is the valuable judgement of the SG ? Optimisation of energy production, plus better visibility are key words.
Examples for using SG: light management in the Cities (currently 35% of the energetic bill) and loading station for electric vehicles (electricity coming from overproduction).
Application of the SG at short term: problem due to ineffective or too old equipment, not convenient for SG management.
At long term: willingness to create the energetic mix with the Cities, but difficulties to control the production curves.
Conviction of GDF SUEZ: the solution is to build smart models that can mix the energetic resources; and to develop locally these SG as much as possible.
Example of the station of BOUGIVAL: mutualisation of the energetic platforms.
3rd Speaker: Hervé RANNOU - ITEMS INTERNATIONAL
According to him, the European strategy for 2050 is reachable only if SG are implemented.
At the same time, necessity to develop the energy storage.
Electricity management has to be decentralised, due to renewable intermittent energy (problem of balance if centralised).
Applications :
- Smart meter for houses and buildings
- Local energy aggregators
The city will collect all the local data (and no more only the subcontracted services)
Problem: the SG have to be inter-operable (whatever the subcontracted service)
USA: Grand Rapids and Green Button
CHINA: big investment (45 MM€) in SG
COREA: want to be world leader within 5 years.
4th Speaker: Gilles BERNARD - ERDF (power supplier)
Issues of power supply:
- frequency (hertz) and Voltage (V) have to be balanced any time
- Renewable energy (windmill, photovoltaic) induce variation in production.
The windmill fields’ increase is equivalent to 1 nuclear plant per year in France.
To manage the variations and extreme situations, energy storage is ideal but expensive (hydraulic, compressed air, electrochemical batteries). Once again, the local storage (in building) could be the solution.
The 1st SG ever applied is off-peak and during-peak hours (for 45 years in France). The 2d SG is the loading station for electric vehicles.
He stresses that the key word for SG is OPTIMISATION.
Regarding the standards (normative), necessity will be to normalise the systems and no more the elements of the systems.
5th Speaker: Murat AHAT - UVSQ - PRISM
Is working on "Programme Gare". The mathematic modelling is to be completed in 2013. Simulation will follow.
