Integrated ICT-platform based Distributed Control (IIDC)
INTEGRAL objective:An integrated ICT platform for
large-scale distributed control
of DER
Key outcome:• Industry-quality reference solution
– Reference implementation
– Technical specs
– Technology for large-scale distributed control, coordination and optimization
– Service-oriented Information Architecture
• Based on commonly available ICT components and standards• Field validated (under normal, critical, and emergency conditions)

• Adopting theory of economics
• Agents competing with one another
• System should handle local processes as well global
• Agents cooperating in order to achieve goal
• Solution should be fast• Sub-optimal solution allowed
• Agents cooperating to prepare grid parts to be switched off

Field test C: Emergency Conditions & Self-Healing Capabilities
• F: Grenoble DER, Urban/industrial, Rural grid cells, + PREDIS analysis & control facility for DER
Reduced ratio: power: 30kVA/30MVA Voltage: 400V/20kV
INTEGRAL ADDRESS Workshop, Paris 09 June 2010 6
Field Test B: Grid Stability under Critical Conditions
• ES/GR: extended microgrid with variety of DER devices
INTEGRAL ADDRESS Workshop, Paris 09 June 2010 7
Field Test A: Normal Operation & Commercial Balancing
NL: > 100 DER/RES devices in dozens of family houses and various other buildings, run as VPP

INTEGRAL Conclusions
• A common ICT Framework for active distribution networks is needed and possible
• INTEGRAL is going to fulfill this need– Incl. results in terms of commercializable technology
• This is a key component of Smart Grids in Europe• And this will bring us much closer to the required
“Internet-like” electricity grid and networks
