AC Power Geometry Summary

BlueChips treats AC power behavior as a boundary and operator problem, not only as a sampled-fault history problem.

The public AC power work connects measured voltage phasors to Dirichlet traces, injected current to Neumann flux, and the bus admittance matrix to a finite terminal Dirichlet-to-Neumann map. It also frames incidence assembly as port gluing and Ward/Kron reduction as a Schur-complement operation on hidden terminals.

This numerical basis gives grid reviewers a way to inspect currents, branch flows, residuals, active-set checks, and certificate conditions from a physically meaningful operator frame.

The current public evidence includes IEEE 118-bus certificate framing and AC-OPF residual and lower-bound language. Program-specific grid models, operating data, and customer-specific assumptions remain controlled review material.
