Stochastic optimization of multireservoir operation: The optimal reservoir trajectory approach
Bibliographic record
Abstract
The paper presents a new method for determining the optimal operating policy of a power system of several reservoirs in series. The method, called optimal reservoir trajectory (ORT), is based on the following fact: Raising the level of a reservoir feeding a power plant is profitable as long as the gain due to the higher head is greater than the loss due to the additional spillage. There consequently exists a reservoir level at time t at which the expected energy generation is maximized. The task of ORT is to find this level and use it to operate the reservoir. The problem is more complicated for several reservoirs in series since the optimal level of each reservoir is a function of the levels of all the other reservoirs. The paper shows how to solve this problem and presents the results obtained for systems of two, three, and seven reservoirs. The results for the systems of two and three reservoirs are compared with those obtained with stochastic dynamic programming.

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.
