Groene ICT&Duurzaamheid 2013
The challenge – designing participation for sustainability

Participation in social-technical systems, systems that adapt

In the energy system
![Page 5: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/5.jpg)
Networks in which self-organization is based on local coördination
![Page 6: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/6.jpg)
Traditional energy market
Energy flows one direction from a
few big producers to many small
consumers (and industries).
![Page 7: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/7.jpg)
• The situation is changing
• Distributed (green) generation
wind turbines, solar panels, etc.
• Consumer becomes producer.
![Page 8: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/8.jpg)
• Role power companies is
changing;
• Ability for consumers to sell
power to each other.
![Page 9: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/9.jpg)
• Each entity is represented by a
software agent;
• Agents can operate semi-
autonomously to negotiate
agreements to buy and sell
energy.
![Page 10: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/10.jpg)
• But the real market is more
complicated;
• More agents, more
communication.
![Page 11: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/11.jpg)
• But the real market is more
complicated;
• More agents, more
communication.
![Page 12: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/12.jpg)
• Single agents can’t compete on
the large market, smaller
dynamic organisations are
more effective.
![Page 13: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/13.jpg)
• They acquire autonomy.
![Page 14: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/14.jpg)
• Organisations negotiate with
each other.
![Page 15: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/15.jpg)
• Organisations negotiate with
each other and change
![Page 16: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/16.jpg)
Technological self organisation at the level of the prosumer, based on communication
![Page 17: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/17.jpg)
But …. for citizens to be able
to take responsibility and to act,
to participate,
socio-techical self organisation is needed.

The first smart grid city in the US: Boulder, Colorado
![Page 27: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/27.jpg)
Boulder
• Boulder has a very highly educated population
• Environmental concern high on their agenda
• National Renewable Energy Labs (NREL) leadership
• “Boulder is just one big technology magnet when it
comes to anything to do with alternative energy,
conservation and end use efficiency (Mauldin) ”

The level of autonomy
is the city.
![Page 30: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/30.jpg)
The level of autonomy in another case
is the community.
![Page 31: SGI13 - Vergroenen dóór ICT - Computersimulaties in de energiesector - Frances Brazier (TU Delft)](https://reader034.vdocuments.us/reader034/viewer/2022051513/547d77d3b4af9fea158b53de/html5/thumbnails/31.jpg)
