The goal of residential load management is to manipulate theelectricity demand of a group of consumers to matchsome desired shape. Effective load management needs two types of controls: systemic and local. Systemic controlmanipulates the aggregate power by signaling the consumers. Local control determines how the power consumerreacts to the signals. I present a price responsive intelligent thermostat for use in local load management. Further, Iexplore two types of systemic control using electricity price as the control variable. The first approach is to identifythe system using a low order model and apply traditional control techniques. The second approach makes use ofgame theory to auction the electricity to the consumers. Both methods enable reliable and robust high resolution loadmanagement.
