Grid-Connected PV + Battery AC Nanogrid with EV Integration for Increased Resilience
Bibliographic record
Abstract
This work concerns a three-phase grid-connected AC nanogrid with PV generation and battery storage. The system is based on SMA Sunny Boy (SB) and Sunny Island (SI) inverters with a Data Manager for monitoring and control. It also includes an EV that can be charged through a standard 208V unidirectional charger when the grid is available. A low-cost single-phase unidirectional Vehicle-to-Home (V2H) inverter, that communicates with the BEMS of the EV, is available at the site. It can supply isolated loads but not to operate in parallel with the PV + battery three-phase system. To allow the EV to support the nano-grid, the V2H is connected through a fourth SI (SI4) to charge the stationary battery. An energy management scheme is proposed for extending load supply following a transition from grid connected mode to islanded mode. It includes not only EV battery support but also load shedding scheme to manage the SOC of the battery. Experimental results are presented.

How this classification was reachedexpand
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.
