Abstract

fetched live from OpenAlex

Voltage rise is a significant challenge in the application of high-penetration solar photovoltaics (PV) to transmission systems. One explanation is a mismatch between PV power and load demand, which occurs regularly in Japan around April and May. Voltage violations occur when voltage levels exceed the allowed limits. To prevent voltage violations, many methods have been proposed, including volt-VAR control on inverters. The effect of employing a dynamic volt-VAR control rather than a static volt-VAR control in a high-penetration photovoltaic (PV) system is compared to that of using a static VAR compensator (SVC) in this study. The reactive power involvement of the PV inverter can be adjusted using dynamic volt-VAR control, which takes into consideration the inverter's available reactive power capacity. The amount of available capacity will influence how forceful the control is, which will be reflected in the droop gain. The controls are tested on the transmission system for a year to assess the number of uncompensated voltage events. The number of violations that the control cannot compensate for affects how much reactive power the SVC must provide.

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.
