Economic viability of price arbitrage operation of vanadium redox battey in Alberta's energy market
Bibliographic record
Abstract
With the rising need for energy storage facilities in power systems of various jurisdictions, it is imperative to investigate the profitability of operating energy storage facilities. This paper assesses the economic viability of a transmission-connected Vanadium Redox Battery (VRB). The system under consideration has a power rating that is large enough that the impacts of its operation on the pool price in the Alberta electricity market should be considered. Using 5 year historical price data, we run a self-scheduling mixed integer linear programming (MILP) optimization model to estimate the maximum possible operational profit operating in Alberta's “Energy Only” market. The rate of return on the investment considering 2011 capital cost estimate and forecasted 2020 cost estimate are calculated, based on the simulated cash flow. The predicted ROI is shown to vary significantly depending on the window chosen as “typical” cash flow.

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.
