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
