Detailed modeling and response of demand response enabled appliances

Proper modeling of end use loads is very important in order to predict their behavior, and how they interact with the power system. This includes voltage and temperature dependencies, power system and load control functions, and the complex interactions that occur between devices in such an interconnected system. This paper develops multi-state time variant residential appliance models with demand response enabled capabilities in the GridLAB-D^TM simulation environment. These models represent not only the baseline instantaneous power demand and energy consumption, but the control systems developed by GE Appliances to enable their appliances to respond to demand response signals and the change in behavior of the appliance in response to the signal. The DR enabled appliances are simulated to estimate the capability of smart appliances to reduce peak demand and energy consumption during grid events.
