Demand response, a cornerstone of smart-grid technology, lets consumers participate directly in energy markets by limiting their energy use during periods of emergency or peak demand. In a direct-control demand-response approach, an electricity service provider (ESP) offers consumers discounts or other incentives if they agree to let the ESP send load-shed instructions (LSIs) to specified appliances. For instance, an ESP might adjust the set points on an air conditioner's thermostat. Direct control can save consumers money and provide ESPs with valuable tools for controlling energy generation costs and grid stability. But these benefits depend on the LSIs producing the expected response from appliances. READ FULL ARTICLE (pdf) »
