Abstract
Remote communities are largely supplied by diesel generating plants. With weak grid and sparse communities over a large geographical area, photovoltaic distributed generation (PVDG) with battery energy storage systems (BESS) can be a viable alternative to grid upgrade while reducing dependence on fossil fuel based generation. This paper presents results of a research study for improving the hosting capacity of distribution systems in remote communities in the northwestern part of Canada. The proposed iterative approach seeks to exploit untapped potential of existing grid infrastructure along with the four-quadrant operation of BESS to maximize the feeder's hosting capacity. The proposed approach uses the headroom of overvoltage limit made available by several voltage regulators in the remote feeder to increase its hosting capacity by as much as 25%. Based on simulations with annual load profiles and site- specific PV generation profiles, it is shown that BESS can further improve the feeder hosting capacity by up to 60% with reactive power support. A comparison is also drawn between the options of grid-upgrade versus the use of BESS for improving hosting capacity. Three BESS technologies are compared with their cost metric for this application.

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 it
