Abstract

fetched live from OpenAlex

Overvoltage resulting from the high penetration of photovoltaic (PV) sources in distribution networks is a major challenge. Approaches to mitigate such overvoltage conditions include curtailment of PV active power and the injection of reactive power by PV inverters. This paper proposes a centralized control strategy to optimize the Volt-Watt and Volt-Var profiles such that active and reactive power of all PV inverters are controlled to not only to mitigate against overvoltage conditions but to do so in a manner where curtailment of active power is equalized or balanced in a fairly manner across all inverters. The Imperialist Competitive Algorithm (ICA) algorithm is used to optimize the objective functions. MATLAB and Open DSS software are used to simulate the grid model and optimize goals.

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.
