A Comparison Study on Time Series Forecasting Given Smart Grid Load Uncertainties
Bibliographic record
Abstract
The trade-off between energy generation and its consumption is usually a difficult task for electricity power grids, since the data obtained from this system tied to uncertainty occasioned by seasonality and natural environment disturbances. Therefore, efforts have been made on the construction of Smart Grids, i.e. intelligent energy networks, which combine Computational Intelligence with the electricity power grids to improve the balance between energy generation and its consumption. For that, Smart Grids controllers have to be aware of future loads, and the prediction of this data must be very accurate to provide an efficient decision support. Since Smart Grid's energy consumption data varies over time, following a time series distribution, we present a comparison study over different time series forecasting in order to evaluate which one would achieve better accuracy in energy distribution. Our investigation was carried out using the Smart Grid of Ontario, Canada. The algorithms used on this experiments were the Adaptive Fuzzy Neural Network (ANFIS), Recurrent Neural Networks (RNN), Support Vector Regression (SVR), Random Forest and SARIMAX. The ANFIS algorithm had outperformed the other approaches, delivering more accurate results.

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.
