Abstract

fetched live from OpenAlex

This thesis investigates the impact of electric vehicle (EV) charging on distribution power systems through the following two tasks. The first task is to build the model of EVs connecting to the grid. Based on this model, the impact of EV charging on the distributed system at the neighborhood level is analyzed on both summer and winter peak days. These impacts are evaluated by taking into account the limitations of the rated transformer capacity and secondary drop lead current. In addition, as a practical concern for the power grid, the transformer ageing cycle is also investigated when EVs are penetrated into the grid. The other task is to investigate the impact of EV penetration across the entire distribution system. The EV charging impact on a feeder of the distribution system of Hydro Ottawa is assessed by considering the feeder unbalance and energy loss.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
