Abstract

fetched live from OpenAlex

The growing integration of Photovoltaic (PV) systems into distribution networks has limited visibility for system operators. Most small-scale PV installations, particularly behind-the-meter systems, are not monitored, making them effectively invisible to utilities [1]. Unregistered rooftop installations or decommissioned systems that may not be recorded can lead to significant gaps in utilities’ records, as observed through interactions with utility partners. This lack of visibility impedes the ability of network operators to ensure proper power flow, system operation, and efficient management of local energy resources. This highlights the need for improved methodologies to gauge and integrate these systems more effectively, especially at the transmission feeder level, where feeders cover large geographic areas [2], which is the main focus of the current poster.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
