Accordingly, the corresponding impact of employing different machine learning(ML) algorithms, with sliding-window and offline training schemes, for hour-ahead baseline load prediction has been investigated and compared. Using a smart meter measurements dataset,training w indow sizes and the most promising pipeline for each building category are first identified. Next, the consumption profiles of five buildings (belonging to each category),w ith the regular operation (baseline load) and w hile offering flexibility, are physically simulated. Finally, the identified pipelines are used for predicting the baseline loads,and the resulting error in estimating the provided flexibility is determined.Obtained results demonstrate that the identified most promising prediction pipeline (extra trees algorithm w ith a sliding w indow of 5 w eeks) offers a notably superior performance compared to that of offline training (average R2score of 0.91 vs.0.87).Employing these pipelines permits estimating the provided flexibility w ith acceptable accuracy (flexibility index’s mean relative error betw een-2.45%to+2.79%),permitting the grid operator to guarantee fair compensation for buildings’ offered flexibility.
