Driver for changes - Demand by Society
100% share of RE in the heating sector by 2035

Solution – Renewable Energy Sources

Resulting challenge – Fluctuations

5
The proposed solution – Smart Grid
• Electrification
• From centralized to decentralized production
• But still demand for stabilization

The Concept of Scale of CITIES
Focus on Cities where all grids are close, demand is large

Political Structuring
The City
Why the Scale of Cities?City = Hub of networks/Grids
Energy System – District Heating (A network)- Electricity

Flexibility from buildings (single and aggregation)
Flexibility though
• heat pumps in district heating
• through storage (expensive, additional costs)

Even more Grids …
Energy Grids + Internet + Intelligence + Organisations + Humans
There is much more

Smart City = Complexity
Energy Grids + Internet + Intelligence + Organisations + Humans
We cannot handle this complexity to find sustainable and robust solutions
We need Science that can manage these complexities

From Smart City To Smart Society
We handle the big grids individually quite well
We are on the way to handle ”big data” (as shown at this event)
We need to master
Integration
Intelligence
We don’t know how-to:
combine models, methods and tools
do science in this complexity
• where theories are to be combined in valid ways
• where numerical methods are scalable
• etc.
We need to advance science
in it’s own right
