Blueprint: Failure-Surviving Village Microgrid (from DOI 10.5281/zenodo.24108691)

Design blueprint for the failure-surviving village microgrid designed in the source paper (DOI 10.5281/zenodo.24108691): a village of 60 households supplied by a 60 kWp solar array, 180 kWh of usable battery storage and one shared 15 kW backup generator, arranged as four independent clusters of 15 households, each with a 15 kWp sub-array, a 45 kWh battery string, a 12 kW inverter, a direct-current bus carrying critical loads without passing through any inverter, and inter-cluster ties carrying up to 2.4 kW. DESIGN BLUEPRINT - SIMULATED, NOT MEASURED - NOT BUILT. In the source hourly simulation of a low-sun week (mean 2.11 peak sun hours per day), the clustered design serves 72.3% of demand through a dead inverter where a conventional same-capacity single-plant design serves 0.0%, and 72.3% where the conventional design serves 23.6% after the loss of the only technician; the clustered design costs $155,300 against $136,000, a premium of $19,300 in total, $321.66 per household (14.19%). Full build specification: four-cluster architecture, bill of materials at the source quantities and unit prices, energy management policy (tier-order serving; storage reserve thresholds at 45% and 20% state of charge; generator limited to 4 running hours per day), installation and assembly sequence, operating envelope, complete failure-mode results, tolerances (none are specified in the source paper, and none are invented), maintenance as specified in the source paper (fault isolation and same-day bypass by a village operator; no calendar schedule is stated in the source), and an explicit list of every figure the source paper does not specify, including module wattage, battery chemistry and cable sizes. Every quantity is from the source paper or derived from its parameters by the accompanying compute.py (derived items marked). Civilian village energy supply only. AI use disclosed: this blueprint was drafted and its calculations scripted with the assistance of Dave, an artificial intelligence system, under the author's direction; the named author reviewed the work and takes responsibility for its contents. No hardware was built or tested.
