Abstract: Various innovations for a transactive control framework with heterogeneous devices such as refrigerators, air conditioners, water heaters, and clothes dryers, or components of such systems/units, are presented. For example, an aggregator for the transactive control framework receives bids from device controllers for heterogeneous devices. Different bids can reflect different behaviors of heterogeneous devices under one transactive control framework, which allows the heterogeneous devices to participate in the same ancillary service market for power. The aggregator determines a cleared price value, then broadcasts the cleared price value and a regulation signal to the device controllers. The device controllers can use a stochastic decision-making process to regulate power utilization by the respective heterogeneous devices, such that the aggregate behavior of the controlled devices tracks the regulation signal.

Abstract: Calibration of building energy simulations with performance data is accomplished by introducing corrective heat flows. A building is modeled on a simulator with descriptive inputs derived from a building audit. The performance predicted by the simulator under the measured driving functions is compared with the measured performance (e.g., of indoor temperatures and/or energy use). Corrective heat flows are calculated from calibration parameters and primary heat flows. The corrective heat flows are then incorporated as additional internal gains and applied to the simulator to minimize the differences between predicted and measured performances. Performance of Heating, Ventilation, and Air-Conditioning systems is included by introducing and estimating additional parameters.
