Abstract
Summary form only given. This paper proposes a control strategy to enhance transient performance and stability of a droop-controlled active distribution network. The dependency of dynamics on the droop gains, steady-state power flow, and network/load is studied in a droop-controlled distributed energy resource (DER) unit. These dependencies result in poor transient performance or even instability of the network in the event of a disturbance in the system. To eliminate these dependencies, a gain-scheduled decoupling control strategy is proposed which reshapes the characteristics of conventional droop by means of supplementary control signals; these control signals are based on local power measurements and supplement the d- and q-axis voltage reference of each DER unit. The impact of the proposed control on the DER and network dynamics is studied by calculating the eigenvalues of a test active distribution system assuming proposed control. The proposed control is shown to stabilize the system for a range of operating conditions. The effectiveness of the proposed control is further demonstrated through simulations carried out in the PSCAD/EMTDC software environment, on the active distribution system under study.

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
