1 Community - 2 Concepts: Questions & Models

• Level of energy supply from local potentials and from the outside:

heat (yearly amount), electricity (effective power levels, yearly

amount), fuel (yearly amount)?

• Effects on electricity residual loads by different options for supply and

interconnection?

Spatial modelling of network based solar heat supply via

geographical information system (demand, roof area)

Hourly based simulation of heat, traffic and electricity demand

and supply
