Enum IslandReferencePolicy 

#[non_exhaustive]
pub enum IslandReferencePolicy {
    Stated,
    PerIsland,
}

How normalization and BalancedNetwork::assign_island_references treat the reference buses of a network with several islands.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Stated

Keep the reference buses the case states. Normalization designates one only when none survives anywhere, and BalancedNetwork::assign_island_references changes nothing.

PerIsland

One reference per island, on a bus that hosts an in-service generator. A stated reference that hosts none is demoted first. An island left with no reference takes the bus of its in-service generator with the largest pmax (the smallest bus id breaking ties); an island left with several keeps the one with the most generation and demotes the others; an island with no in-service generator cannot be solved and is de-energized. Normalization under this policy picks the same reference buses.
