Abstract
With the rapid growth of wind power penetration in power systems, researchers focus on methods to accurately model wind generators in power flow studies. There are several accurate wind generator models which capture the voltage dependence of power output per each phase of wind generators. These models have been built using individual models of all the constituent components of wind generators. Furthermore, these models comprise complex nonlinear equations and hence inevitably slow down power flow studies. When wind farms are modeled with this approach, they become very complex and cumbersome to be integrated into power flow studies. On the other hand if the power output of a wind farms is simplistically assumed as fixed injection value neglecting the voltage dependence of power output per phase, the resultant power flow solution will not be accurate due to over simplification. In this paper a new wind farm model is built using Artificial Neural Networks (ANN). The procedure of building ANN models is explained using a small wind farm with five wind generators. The ANN wind farm models estimate power output per phase using three-phase voltages and wind speeds. A power flow study with this ANN model, a simple fixed power model and a detailed nonlinear model is reported in this paper with sufficient comparisons. The proposed ANN model is 80 times faster than a complete nonlinear wind farm model and as accurate as the nonlinear wind farm model.

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
