Abstract

fetched live from OpenAlex

Renewable energy systems have been implemented globally to help lower carbon emissions; for example, pumped hydro energy storage (PHES) is a system that helps mitigate peak loads on electrical grids to reduce dependency on fossil fuel energy generation. As a form of energy storage, PHES involves using two water reservoirs at different elevations to generate electricity at times of peak demand. Integrating PHES near wind farms allows the required water-pumping electricity to be supplied by wind power, rather than fossil fuels. A spatial analysis was done using ArcGIS Pro to determine the most ideal sites for PHES within close proximity to wind farms in Nova Scotia. Five potential sites were identified, and map layouts were produced showing conceptual models of PHES at these locations throughout the province. Due to the topography of Nova Scotia, development of PHES is not feasible at many potential sites. Five suitable sites were ranked based on environmental and technoeconomic costs; the Barrachois Wind PHES hybrid project was ranked the highest, followed by the Digby, Ellershouse, Maryvale, and South Canoe wind energy sites. The study concluded that integrating PHES into wind farms in Nova Scotia would be a useful method for boosting electrical grid stability, and attaining emissions reductions targets throughout the province.

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.
