Abstract
An efficient load-flow algorithm is required for automated distribution systems for operation and control and for planning and optimization. This article presents a robust load-flow algorithm for solving balanced radial distribution feeder. It solves simple algebraic recursive equation of receiving end voltage. Branch and node numbering techniques used do not require any specific training, and any arbitrary numbering scheme will lead to the solution by taking the same computer memory and computational time. In the algorithm, composite load model has been used because loads are voltage dependent in distribution systems. Load growth is also incorporated in the algorithm, as it is required by engineer for distribution systems expansion planning and operation. C++ program has been developed, and several power distribution networks have been successfully tested. The results are compared with those of other research and are found to be superior in terms of convergence and execution time, taking a lesser number of iterations. The proposed algorithm is found to have superior convergence pattern, and convergence is observed to be insensitive to type of load model, size of network, and R/X ratio of feeders. In the four different types of load models considered, the proposed algorithm took only four iterations to converge, whereas others have reported as high as seven iterations in the case of exponential load, and their convergence pattern varies with the load model.

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
