Abstract
Large scale interconnection of single-phase distributed generation (DG) with utility distribution grid can cause current unbalances resulting in voltage unbalances. The methods of Newton-Raphson and Gauss-Seidel are generally used for power flow's calculation. However, these methods are sometimes complex and their convergences may be long. The iterative process of Newton-Raphson method, using the admittances matrix is practically independent of bus bars number. The calculation's time of Gauss-Seidel method increases almost proportionally with the bus bars. In addition, the calculation's time of the Jacobien's matrix and each iterative process are considerably long for the Newton-Raphson method. In this paper, a method based on the impedance order reduction and identification of the power flow's direction is presented. Analytical and simulation studies were performed in order to validate the accuracy of the proposed method. For an application network model, the voltage unbalances are calculated. The results are compared with those of two commercial softwares.

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
