Abstract
Hybrid renewable energy sources (RES)-diesel systems are now being considered as an economic, attractive and clean option for remote isolated microgrids, to offset diesel consumption by displacing generation from conventional units; however, system security and stability is a challenge as the penetration of RES increases. In this context, Demand Response (DR) can be used to increase grid flexibility, improve efficiency, and facilitate the penetration of RES. Thermostatically controllable loads (TCLs), i.e., electric water heaters (EWHs), air conditioners (ACs), and ground source heat pumps (GSHPs), are ideal candidates to participate in such a DR strategy, since their power consumption can be controlled without affecting consumer comfort. Therefore, this paper presents novel, computationally efficient, and adequate thermo-electrical dynamic models of ACs and GSHPs, along with an existing model of EWHs, to adapt and improve a decentralized DR strategy for Direct Load Control (DLC) for primary frequency regulation in hybrid isolated microgrids. Different cases studies are presented for a real microgrid to analyze and compare the system frequency response and determine the adequacy of the proposed approach and models, demonstrating their effectiveness for primary frequency control provision to facilitate higher RES penetrations.

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
