}

What a Measurement is attached to.

Variants

Bus(usize)

A bus: a voltage measurement, or the injection of the loads and generators attached to it.

This is not power-grid-model’s “node injection” — see Target::NodeInjection. gridoxide models sources and shunts as part of the network rather than as appliances, so they do not appear in this quantity at all.

BranchTerminal

One terminal of one branch, indexed as in branch_flow::branch_params.

Fields

branch: usize

terminal: Terminal

SourceInjection

The power a source delivers into its node.

power-grid-model treats a source as an appliance at the node, but gridoxide synthesizes a virtual slack bus behind a source-impedance branch, so the source’s power is that branch’s flow rather than any bus injection. branch is the synthesized branch, from gridoxide’s PgmNetwork::source_branch_idx.

Fields

branch: usize

ShuntInjection

The injection of the shunts attached to a bus.

Shunts are stamped into the Y-bus diagonal, so like sources they are structural here and absent from Target::Bus. Shunts on one bus share a single Y-bus entry and cannot be told apart afterwards, so this is their total.

Fields

bus: usize

NodeInjection(usize)

power-grid-model’s node injection: the sum of every appliance at the bus — loads, generators, sources and shunts alike.

Equals Target::Bus plus the source and shunt injections at the same bus, which is what makes it a distinct measurement function rather than a relabelling.

BranchTerminalCurrent

A current sensor on a branch terminal.

Separate from Target::BranchTerminal rather than a flag on it, because the frame changes the measurement function and because se::iterative keys its row builder on Target — which makes power-grid-model’s “no mixing power and current on one terminal” rule fall out of the type rather than needing to be enforced downstream.

Fields

branch: usize

terminal: Terminal

frame: AngleFrame
