Abstract: This paper presents an optimization process for multiple-building load aggregation based on statistical models of building dynamics. The aggregation process is modeled as a central optimizer and participating buildings as unit simulators. By learning from wholebuilding simulation results, unit simulators describe individual buildings' base-load profiles and responses to control parameter changes. The optimizer makes supervisory control decisions based on a centralized objective function which takes inputs from individual simulators. A non-linear mathematical optimization problem is formulated and solved using an interior-point-method commercial solver. Results are compared to simple cases for which optimal or near-optimal results are relatively easy to find. The expansion of the analytical framework is discussed.
