Economic dispatch in microgrids using compromise solution method
Bibliographic record
Abstract
In this paper, we evaluate a multi-objective-moving-horizon-optimization (MO-MHO) approach as an instrument for improvement of economic dispatch in microgrids. In particular, we investigate the effect of adaptation of the multi-objective optimization strategy used in the moving horizon framework on the end result of the economic dispatch. Power dispatch in microgrids is inherently a high-dimensional problem often cast as a mixed-integer stochastic program with conflicting objectives. Implied is the fact that exhaustive exploration of the whole Pareto front in a related multi-objective approach is not a computationally tractable decision tool. It is thus argued that it is preferable to represent the problem as a bi-objective optimization problem with the two costs grouping the least conflicting components. The solution method for the optimization problem over a window “looking into the future” can then be selected or adjusted in real time by employing an independent set of assessment functions evaluated along the trajectories of optimal multi-objective solutions already implemented over a window in the past. The proposed strategy is applied to a case study of a remote microgrid. Its performance is evaluated based on simulation results that suggest that choosing the compromise solution of the MO-MHO problem may be superior to the usual scalarization methods.

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.
