Modeling EV fleet Load in Distribution Grids: A Data-Driven Approach
Bibliographic record
Abstract
This paper proposes a modeling method for electric vehicle (EV) charging loads in the distribution grids. Different from previous work that modeling under general car travel distance based statistics, we advocate using real world power consumption data, which collected from the charging port meters. The essential charging behavior characteristics were retrieved from such high-resolution data. The vehicle behavior indicates that the distribution of the initial SOC when EV put into charge is not necessarily Iognormal type. Possible causes for such non-ideality are discussed. The new model proposed here can incorporate the stochastic nature of EV charging to improve researchers' analysis. An explicit description of the model along with its operating dynamics and a practice to analyze the total power load of a mid-sized EV fleet is provided. We demonstrate that the proposed model can more correctly reflect the total power need of a fleet and can be adopted as a load-forecasting tool of EV fleet charging load.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
