An Agent-Based Model Applied to Brazilian Wind Energy Auctions
Bibliographic record
Abstract
This article, for the first time, adopts the agent-based model simulation technique to analyze the pricing process of energy in the Brazilian electricity market (auctions). Within this model, it is possible to analyze how the energy price is affected when a government intervention is observed through the increase in number of public companies participating in the auctions. In this paper, auctions of new and reserve energy of wind power are simulated. Through this model it is possible to compare the choice of bids from participating sellers in the auctions, categorized in two different groups: public and private companies. The agents (sellers) participate in the auctions by learning from the historical and simulated auctions that is regulated by the Brazilian government. Learning is performed through the usage of a variation of the Q-learning algorithm, which provides the sellers the optimal price-bid considering the conditions presented, which means that this price-bid will provide them the maximum reward possible. The results clearly show the average price difference between both generator profiles. In addition, it is possible to state that the price of energy changes due to the relative participation of public or private sellers in the auctions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
