Enum LinearIslandStatus 

pub enum LinearIslandStatus {
    Solved,
    Singular,
    NoReferenceBus,
    SolvedMultipleReferences,
}

How one connected component’s constant-admittance solve turned out.

Variants

Solved

Solved; this island’s PQ bus voltages satisfy its linearized equations exactly.

Singular

The reduced system was singular, so this island’s voltages were left at whatever the caller supplied.

NoReferenceBus

No Slack bus, so there is nothing to reference the solve against. Pinned to V = 0 by network::mark_unreferenced_islands.

SolvedMultipleReferences

Two or more Slack buses. Unlike the Newton path — which leaves such a component live and warns that the result may satisfy neither reference — this solves it, because the system stays linear and well posed: each fixed voltage simply contributes its own term to the right-hand side. The result is the true solution of the circuit as described, which is a meaningful answer to an arguably ill-posed question.
