“Modelling Electrical Demand in Georgia”
One of the challenges of managing the power grid is responding to changes in demand. Since there is only limited capacity for electricity storage, the supply must be matched to demand in real time. To simplify this problem, this project seeks to create effective models of power demand, moving along two tracks. The first involved improving an existing neural network model. This model was very accurate but did not consider the effects of human events such as holidays. An analysis of these events revealed clear effects on usage which were incorporated into the model, improving its accuracy. The second and ongoing effort focuses on developing an agent-based model of demand. Instead of being fit from past usage data, this model will simulate the decisions of power users that make up demand. This will result in a more flexible model which can easily be changed to account for unprecedented situations or novel types of usage.

“Aircraft Conceptual Design Tools Integrated with Model-Based System Engineering (MBSE) Models"
Aerospace systems have become increasingly complex with time and traditional document-based systems engineering can be inefficient due to the many standalone models for the system. MBSE focuses on creating a unified shared system model that better manages this complexity. This research focused on integrating conceptual design analysis tools into System Modeling Language (SysML) models using MATLAB and exploring the analysis capabilities of such model.
