DREAM Team Publications
In order to eliminate the need for new costly power plants, the State
of California is exploring a new source of electricity savings: the
reduction of peak demand. Measures to reduce the peak demand for
electricity are termed 'demand response' (DR). As part of the effort
to increase demand responsiveness, the California Energy Commission is
currently constructing a new policy to require DR-enabled thermostats
for new residential construction in California.
Before demand-response systems can be effectively deployed on a wide
scale in the residential sector, several issues must be resolved. One
group of the DRETD team is working on the infrastructure of
communications (Prof. Paul Wright, Prof. Jan Rabaey). Another group is
developing metering infrastructure (Prof. Richard White), and yet
another group is working on energy scavenging (Prof. Paul Wright). The
DRETD Thermostat and Controls Group (Prof. Dave Auslander, Prof.
Edward Arens) is developing controls: a demand response thermostat.
This low-cost demand-responsive electrical appliance manager (DREAM)
exploits wireless technology and a system of learning (both by machine
and occupant). DREAM automatically responds to price signals so that
the homeowner is not forced to be a "day trader" in electricity.
It accepts the homeowner's preferences for cost versus comfort. This
"thermostat" controls other appliances in the house, such as
electric water heaters, refrigerators, pool pumps, and lights in response
to price signals from the utility.
This website describes the hardware and software developed to test this system.
