THE SEMIAH MOTIVATIONDemand response potentials The operation of wet appliances can

be shifted in time without affecting user comfort.

Postponing the operation of a heat pump for a small amount of time (up to 30 min.) does not affect the comfort but creates a considerable amount of flexibility.

The operation of a micro CHP plant can be shifted in the same manner as the heat pump (shifting operation in time; operate at partial output e.g., 70%; or full power).

Hot water boilers represents an energy buffer, which provide flexibility to the overall power system.

Up to 40% of household electricity

consumption can be shifted

An aggregated demand response need many small contributions of

There is a need to adapt the electricity consumption side to cope with the fluctuations in generation from renewable energy sources (wind and PV).

ICT can be utilized as a cost-effective way to exploit flexibilities in consumption through Demand Response programs: The European research FP7 project SEMIAH investigates scalable demand

response in residential households; The ForskEL project VPP4SGR looks at the integration of building automation

using a combination of direct and in-direct electricity load control; Key challenges in demand response research: user involvement,

scalability, quality of a demand response, new business models – trading flexibility.
