Struct Island 

#[non_exhaustive]
pub struct Island {
    pub buses: Vec<BusId>,
    pub references: Vec<BusId>,
    pub generators: Vec<usize>,
    pub hvdc: Vec<usize>,
}

One AC island: energized buses joined by in-service branches, closed switches, and in-service three winding transformers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

buses: Vec<BusId>

The island’s buses in ascending id order.

references: Vec<BusId>

Its reference (slack) buses, in ascending id order.

generators: Vec<usize>

Rows of the in-service generators on its buses.

hvdc: Vec<usize>

Rows of the in-service HVDC lines that tie it to another island: one terminal on its buses, the other on another island’s.

Implementations

impl Island

pub fn is_supplied(&self) -> bool

Whether an in-service generator can supply the island.

pub fn calc_reference_choice(&self, generators: &[Generator]) -> Option<BusId>

The one reference bus IslandReferencePolicy::PerIsland gives this island, without changing the network. Only a stated reference that hosts an in-service generator counts: the island keeps it when it states one, takes the bus of its largest pmax in-service generator (the smallest bus id breaking ties) when it states none, and keeps the one hosting the most in-service pmax (the smallest id breaking ties) when it states several. None when no in-service generator supplies the island, which that policy de-energizes. generators is the network’s generator table.
