Motivation and Objectives

Despite continuous upgrades and improvements to the systems that form electricity grids, the fundamental operation of these systems has changed relatively little over almost one hundred years. This is, the supply of electricity to the residential, commercial and industrial sectors is based on demand. As the magnitude and diversity of this demand has increased, so too has the size and diversity of generation required to meet our electricity needs. Traditionally, this has meant that generation capacity was built to satisfy peak demand, using layers of myriad generation sources, from lumbering coal and nuclear plants to nimble gas turbines, with widely varying costs and efficiencies. In practical terms, this has created a large disparity in electricity price from hour to hour and underutilization of most generators, as systems are daily brought online to satisfy demand, and taken offline when demand has subsided.

Assuming that neither grid-scale nor distributed storage are deployed at scale for a decade or more and that renewable generation will continue to become an increasing component in the generation mix, the problem becomes one of how best to enable flexible demand side participation of building sited electricity consumers given a mix of traditional and renewable generation.

Historically, resources on the demand side have played a relatively inflexible role in energy markets, requiring grid balancing to be achieved solely through modulation of generating resources. However, buildings can create additional grid flexibility to aid in absorbing the intermittency of variable generation resources. Previous work has demonstrated that significant peak electric demand reductions can be achieved through active thermal energy storage systems and by utilizing passive building mass as a thermal storage medium. Buildings with significant thermal mass may also be well suited to provide ancillary services, including spinning and non-spinning reserve. Recent work has also considered controllable building electric loads for economic dispatch in energy markets, including transmission constraints. As an example, researchers recently demonstrated that chilled water supply temperature could be modified to create responsive changes in electric demand. Frequency regulation in commercial buildings has also recently been investigated. Moreover, combined heat and power (CHP) plants, installed in individual buildings or campuses, can provide both distributed generation and building HVAC services at high efficiencies.

In summary: Through better integration of building and electric grid operations, greater system efficiencies can be achieved by buildings actively participating in energy markets which in turn can enable greater amounts of renewable generation by creating elasticity in the demand for electricity. In addition, buildings can benefit from providing ancillary services through lower utility bills due to energy price arbitrage, demand charge reductions, demand response revenue, and ancillary service revenue.

This interdisciplinary short-course invites attendees from a wide spectrum of backgrounds interested in energy engineering to understand the demand and supply sides of the electric grid system, explore opportunities for better integration of buildings into the smart grid, and quantify the benefits of load side flexibility through hands-on laboratory and computer simulation practice sessions.
