A sustainable energy future rests on the twin pillars of (1) renewable energy and (2) energy efficiency. Renewable energy sources such as solar and wind are intermittent: their generation is uncertain and time-varying. Inexpensive energy storage technologies are required to ensure a reliable electricity supply in the face of such intermittency. An alternative to expensive batteries is “smart loads”. With appropriate control algorithms, the power consumption of air conditioning — and many other loads — can be varied around a baseline. This variation is analogous to the charging and discharging of a battery. Air conditioners and water heaters equipped with such intelligence have the potential to provide a vast and inexpensive source of energy storage: a giant, cheap battery. At the same time, there is an increasingly urgent need to reduce the energy consumption of buildings as well, since they account for 73% of electricity consumption and 34% of CO2 emissions nationwide.
This talk describes the technologies we are developing to reduce energy use as well as to provide virtual energy storage from various loads. The focus of the talk is on the virtual energy storage from air conditioning loads. The key question we address is: how to coordinate millions of buildings to create a giant virtual battery, so that it provides a robust and predictable service to the power grid with minimal communication and computation, while at the same time maintaining building occupants’ quality of service?
