gtopt/line.hpp file

Header for transmission line components.

This module defines data structures for representing AC transmission lines in power system planning models. In DC power-flow (Kirchhoff) mode the reactance determines the flow split between parallel paths. The line also supports capacity-expansion planning.

JSON Example (transmission line)

{
  "uid": 1,
  "name": "l1_4",
  "bus_a": "b1",
  "bus_b": "b4",
  "reactance": 0.0576,
  "tmax_ab": 250,
  "tmax_ba": 250
}

JSON Example (phase-shifting transformer)

{
  "uid": 5,
  "name": "pst_1_2",
  "bus_a": 1,
  "bus_b": 2,
  "reactance": 0.05,
  "type": "transformer",
  "tap_ratio": 1.02,
  "phase_shift_deg": -5.0,
  "tmax_ab": 300,
  "tmax_ba": 300
}

Fields that accept a number/array/string value can hold:

A scalar constant
A 2-D inline array indexed by [stage][block]
A filename string referencing a Parquet/CSV schedule in input_directory/Line/
