Abstract

fetched live from OpenAlex

Carbon emissions mitigation is driving the need to decarbonize different energy systems. Alongside the energy systems decarbonization, there is uncertainty over determining the best goals in terms of cost and emissions. In this work, a hybrid energy system which consists of renewable energy systems, storage systems and a diesel generator are considered to supply the energy demands of an off-grid house. One of the main challenges in off-grid systems is the trade-offs between energy storage and importing diesel. This challenge is due to the variability of both renewable energy resources and the building demands. This paper introduces an energy hub model that is used for the optimal sizing and operation of an energy system. Four scenarios are considered to decide how well an off-grid system works in term of its total cost and greenhouse gas emissions. Our results show that hybrid systems are 35% cheaper (over a 25 year lifespan) than the base case using a diesel generator. This situation gets worse at higher diesel prices, and is helped by lower PV and battery prices, but not in a linear manner. This is illustrated using contour plots that show the impact of different combinations of variables.

Teacher imitation

Not 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.
