Abstract
Supercapacitors (SCs) are increasingly used in energy storage system to tackle the fast power transients. They can be used individually or together with other energy storage units like batteries. In a microgrid, multiple SCs could be installed at different locations without communications among them. This paper focuses on the energy management strategy (EMS) of multiple SCs in a dc microgrid, where the distributed generation units and energy storage units are controlled with the plug-and-play feature. A novel EMS is proposed, which uses the state-of-charge-based adaptive virtual impedance to facilitate the transient power sharing among the parallel SCs without physical communications. The detailed analysis and design procedure are explained based on an example microgrid system with two SCs and one battery energy storage connected in parallel through the dc/dc converters. The effectiveness of the proposed method is verified by both simulation and experimental results.

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
