What Is Demand Response?
Demand response happens when a utility, aggregator or grid operator induces electricity customers to change their usual power consumption patterns through financial or other incentive. Our group's research touches on various facets of demand response programs, which can help the grid operate more efficiently, reliably and with more renewable energy systems.
Communications & Standards
We are helping to increase participation and lower costs of demand response programs with automated communications and standards. Since 2003, our researchers have helped develop an open, interoperable and secure automation and communication infrastructure called Open Automated Demand Response (OpenADR). OpenADR, now a national smart grid standard in the U.S. and gaining international adoption, facilitates reliable and cost-effective signals of electricity price and system grid reliability, allowing facility operators to automate their responses.
Demand Response Resources
We are helping shed light on the potential market for demand response resources and how to help them operate more effectively. Recent improvements in broadband communication allow the faster coordination of demand response resources such as commercial building HVAC or refrigerated warehouse end-uses, so that loads can be dispatched as needed to maintain grid reliability. We are exploring how much demand response is available in the future as new technologies and new markets create more flexible end-use loads.
While electric vehicles help reduce greenhouse gas emissions, the power demand to charge them may have adverse effects on the grid, overloading the distribution system. However, these same load sources can be turned into valuable grid resources with advanced controls and communication. Our research helps evaluate and demonstrate the potential of electric vehicles as electricity storage resources for a number of grid applications, including fast demand response, wholesale ancillary services and behind-the-meter services.
Understanding Electricity Markets
We integrate our technical expertise with analysis to identify market and policy barriers for demand response. Research focuses on how price and reliability signals can be communicated reliably; how facilities can respond automatically when prices vary hour-to-hour, day-to-day and over time; and how these concepts can be used to improve grid stability and facilitate the integration of renewable energy.
Testbed, Tools & Guides
Our researchers have developed a number of tools and guides for evaluating and implementing automated demand response in the market place. The Demand to Grid Laboratory offers a working environment where interoperability of OpenADR-enabled devices and systems can be developed, tested and demonstrated. We are testing the use of OpenADR integrating FLEXGRID's new electric storage and PV systems with FLEXLAB®'s building loads.
