Struct GenCost 

#[non_exhaustive]
pub struct GenCost {
    pub model: u8,
    pub startup: f64,
    pub shutdown: f64,
    pub ncost: usize,
    pub coeffs: Vec<f64>,
}

A generator cost curve (mpc.gencost row).

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.

model: u8

1 = piecewise linear, 2 = polynomial.

startup: f64

shutdown: f64

ncost: usize

Number of cost coefficients (polynomial) or breakpoints (piecewise).

coeffs: Vec<f64>

Raw coefficients, highest order first for the polynomial model: [c_{k-1}, …, c1, c0].

Implementations

impl GenCost

pub fn new(model: u8, startup: f64, shutdown: f64, coeffs: Vec<f64>) -> GenCost

Build a cost row from the values carried after ncost.

Polynomial rows (model == 2) store ncost coefficients. Piecewise linear rows (model == 1) store flattened (x, y) breakpoint pairs, so ncost is half the coefficient count. Use GenCost::with_ncost for malformed source rows or callers that need to preserve an explicit ncost.

pub fn with_ncost( model: u8, startup: f64, shutdown: f64, ncost: usize, coeffs: Vec<f64>, ) -> GenCost

pub fn quadratic(&self) -> Option<(f64, f64)>

(q, c) for the quadratic cost ½ q p² + c p from a polynomial (model 2) row. MATPOWER stores c2 p² + c1 p + c0, so q = 2·c2 and c = c1. Linear rows (ncost == 2) give q = 0. Piecewise (model 1) or cubic and higher return None.

pub fn quadratic_with_constant(&self) -> Option<(f64, f64, f64)>

(q, c, c0) for the quadratic cost ½ q p² + c p + c0 from a polynomial (model 2) row, keeping the constant term that quadratic drops. Linear rows (ncost == 2) give q = 0; constant rows (ncost == 1) give q = c = 0. Piecewise (model 1) or cubic and higher return None.
