Guideline for Verifying IEEE Harmonic Compliance
Bibliographic record
Abstract
With the increase in generation from inverter-based resources (IBRs), harmonic distortion is becoming a larger issue than it has been in the past. Harmonic distortion must be limited in the power grid because it can cause many negative impacts, such as decreased efficiency and equipment damage. The IEEE 519 [1], IEEE 1547 [2], and IEEE 2800 [3] standards describe harmonic distortion limits that various systems should meet. The limits differ based on several factors, including voltage level, interconnection location, IBRs, etc. The organization and complexity of these IEEE standards can make it difficult and time-consuming to identify if a system is compliant with the standards properly. The main purpose of this paper is to act as a guideline for establishing IEEE harmonic compliance, which can be summarized in Fig. 4. There are three steps to confirm system compliance with the IEEE standards. First, data must be measured at the project’s point of interconnection (POI). Second, a statistical evaluation must be performed on the data. Third, these results must be compared to the correct IEEE limits. Each of these three steps can be either unclear or confusing within the IEEE standards for harmonic distortion. This paper discusses these difficulties in detail and establishes a flowchart for identifying IEEE harmonic compliance.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
