On 14 November 2008, at 12:15, Virtual Generator (VGen) formed with:
• Two CHPs (neither spinning): one at Billund CHP plant and one at Hejnsvig CHP plant.
• 3 wind turbines, generating at about 45% capacity.
• 7 online load‐feeders.
The synchronous condensor (SC) and secondary load controller (SLC) are not available to the VGen.
Sequence of events:
• A (12:15): import/export control is enabled with a zero active/reactive set point for the VGen. In response to wind levels, Cell Controller starts only one CHP (Billund unit 1)
• B (12:35): operator increases import/export set point of the VGen is increased.
• C (12:45): the Cell controller brings a second generator (Hejnsvig CHP 1) online.
• 12:45 to 13:02: the VGen works to maintain the set point.
• D (13:02): a zero import/export active set point is requested and the VGen responds accordingly.
Phase 2 Testing: Virtual Generator

Next Steps
• Complete C1 data analysis!• Next phase will include Area 2• Plan to demonstrate:
– Dynamic Cell creation– Sub-cell formation and merging– Virtual Gens for market operations– Automatic topology management– Wind smoothing
• C2 Duration: 2009-2010
