Islanded Microgrid Architecture

An islanded microgrid lets a base generate, distribute, and control its own power with no reliance on a commercial grid, using the fusion unit as one dispatchable source.

What islanding means

An islanded microgrid is a self-contained electrical system that generates and distributes power within an installation's boundary, able to run disconnected from any commercial grid. For a defense site, islanding is the default posture: the base is designed to operate as though the outside grid does not exist.

Roles inside the microgrid

• Generation: the fusion unit as a base-load source, plus backup generation.
• Storage: batteries or equivalent to smooth transients and bridge trips.
• Controls: a microgrid controller that dispatches sources and sheds non-critical load.
• Protection: fault isolation so one failure does not black out the mission loads.

Why the fusion unit is not the whole grid

Because burner availability is 0.86–0.995 versus Tier III's 0.99982, the microgrid must be designed so the mission survives a unit trip. Storage bridges short outages; redundant generation covers longer ones; load-shedding protects the highest-priority loads. The fusion unit is the anchor source, not the entire architecture.

This architecture is standard microgrid engineering applied to a novel source. It is the layer that turns an imperfect generator into resilient installation power — and it is why sovereign power is a system claim, not a single-machine claim.

Islanding as the default posture

A defense microgrid is designed to run islanded as its normal state and to treat any external connection as optional. This inverts the civilian assumption that the grid is primary and on-site generation is backup. The fusion unit anchors the islanded base load, while storage, controls, and redundancy give the island the continuity a single machine cannot.
