Abstract

fetched live from OpenAlex

Active voltage control (AVC) is a widely-used technique to improve voltage quality essential in the emerging active distribution networks (ADNs). However, the voltage fluctuation caused by intermittent renewable energy makes it difficult for traditional voltage control methods to deal with. In this paper, the voltage control problem is formulated as a decentralized partial observable Markov decision process (Dec-POMDP), and a multi-agent reinforcement learning (MARL) algorithm is developed considering each controllable device as an agent. The new formulation aims to adjust the strategies of agents to stabilize the voltage within the specified range and reduce the network loss. To better represent the mutual interaction between the agents, a graph convolutional network (GCN) is introduced. By aggregating the information of adjacent agents, complex latent features are effectively extracted by the GCN, hence promotes the generation of voltage control strategy for the agents. Meanwhile, a barrier function is applied in MARL to ensure the system voltage within a safe operation range. Comparative studies are conducted with traditional voltage control and other MARL methods on IEEE 33-bus and 141-bus systems, which demonstrate the performance of the proposed approach.

Full frame distilled prediction

Teacher imitation

Not 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.
