Appendix C: Changing Tref without Introd... > C.1 Effect of an Increase of Tref

C.1 Effect of an Increase of Tref

Homes participating in a demand-response program accept only temporary changes to their home's temperature. At some point therefore the thermostat temperature must be increased again from Tref −Δ to Tref.

In order to avoid creating any synchronizing event, a possible strategy is to change the thermostat temperature for all homes that reach Tref + H−Δ (Figure C.2).

If Δ/X < H/Y (case of (Figure C.1), the number of active heating systems increases from k.H/X to k.(H + Δ)/X in Δ/X hours: energy demand increases to P(H + Δ)/H, then remains constant, above average, for H/Y−Δ/X hours, then returns to its average value in Δ/X hours.
