Sailing the electric grid through wind and sunshine

ABSTRACT: 
The North American power grid is a giant system made up of many components – generators that generate electricity, transmission and distribution lines that carry it, and loads that consume it, such as lights and air conditioners. For stable and safe operation of the grid, generation and demand (consumption) of electricity must be equal at every instant. This balance is traditionally achieved by control mechanisms at many levels, but primarily by commanding the generators to produce exactly what the grid needs every instant. Renewable energy sources such as wind and solar, however, cannot be commanded in this manner. Their generation is also highly variable. This creates a need for new resources to achieve supply and demand balance. Without such resources, cascading blackouts may occur more frequently.
 
When generation is uncontrollable, one possibility is to control the demand. An obvious choice for flexible demand is buildings, which consume 75% of the electricity generated in the U.S. Due to their large thermal inertia, commercial buildings can effectively act as short-term batteries and tune their demand to match supply with negligible change in the indoor climate.  With appropriately designed control algorithms, all the buildings in the U.S. together can provide much of the required “ancillary service” to the grid. In fact, any flexible load, not just HVAC, can play a role in helping the grid absorb volatile renewable energy sources. In this talk we will describe our current work on developing such control algorithms. Some of these algorithms are being tested in a UF campus building.
