Equivalent Circuit Modeling of Proton Exchange Membrane Electrolyzer Considering Multi-Physics Transients in EMTP-Type Simulators
Bibliographic record
Abstract
The Electromagnetic Transients Program (EMTP) is widely used for simulating electromagnetic transients in power systems. In recent years, applications of electrolyzers in electric power systems have attracted considerable attention because electrolyzers are among the most promising energy-conversion devices for realizing hydrogen production from renewable energy sources while enhancing system flexibility by functioning as controllable loads. With the growing interest in electrolyzers, it would be advantageous to broaden the application of EMTP to include multi-physics transients such as those observed in electrolyzers. This article details the implementation of such an extension for a proton exchange membrane electrolyzer (PEMEL). Analogies between electric, mass transfer, and thermal quantities are adopted to develop an electric circuit model that describes currents, voltages, mass transfer, pressure, heat transfer, and temperature. The PEMEL model considering the interactions of electric, mass transfer, and thermal transients can be readily implemented in EMTP-type programs using existing components from standard libraries. The proposed electric circuit model was validated through comparison with experimental data under both steady-state and transient conditions. The value of the proposed model was illustrated via application to a PEMELbased integrated electrical and gas system.

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.
