Using "Smart Agents" to Save Energy, Fight Global Warming

“Smart agents” have infiltrated Australia’s renewable energy research center. The smart agents are wireless motes the size of a Treo that adorn office walls while other versions are attached to refrigerators, a wind turbine and solar panel arrays. The agents communicate among themselves, analyzing data and adjusting the center’s power systems and air conditioning. For instance, when the smart agent that controls the facility’s solar arrays learns from the weather report that maximum photovoltaic power will be produced around 2 in the afternoon, it will notify the agent that controls the center’s air conditioning. “That agent may say, `I’ll wait until 2 p.m. to turn on the air conditioning when we have renewable energy coming online,' ” said Glenn Platt, the smart agent project leader for the Commonwealth Scientific and Industrial Research Organisation, when the Green Wombat visited the CSIRO Energy Centre this week. Other agents monitor individual offices, observing that one person may prefer warmer temperatures than others. The mote (like the one pitctured at right) will adjust the thermostat for that office, saving on air conditioning costs. 

CSIRO has been trialing the technology with utilities who are interested in installing smart agents in individual homes to control heating, air conditioning and appliances. Each home would be plugged into a neighborhood smart grid, with every house exchanging information with the others about power useage. Managing peak demand is a challenge for utilities – when it’s a scorcher, everyone turns on their air conditioning at the same time – so the agents learn which residents can tolerate higher temperatures and who is at home when. That allows the power company, through the agents, to turn off the air conditioning in a handful of houses for 15 minutes at a time to manage peak demand rather than implement rolling blackouts that take entire neighborhoods off the grid. As the share of electricity generated by solar and wind power grows, Platt expects demand for smart agents to rise as homes, businesses and utilities will need to manage increasingly complex systems to ensure that the cheapest and greenest energy is used a the right times.

Platt’s team is also working on making radio frequency ID chips smarter by incorporating temperature sensors. For example, a smart RFID chip on a box of carrots shipped to Wal-Mart (WMT) would communicate with the agents in a store’s refrigeration cases and storage rooms about the optimal temperature the carrots need, thus saving energy costs. CISRO expects to commercialize its smart agent technology within two years.
