Retrieve SigLinDe Coefficients for Gas Standard Load Profiles

Source: R/slp_gas_reference.R
slp_gas_coefficients.Rd

Returns the SigLinDe profile function coefficients for one or more gas standard load profiles as a data frame. These are the values used internally by slp_gas() and slp_gas_siglinde().

Usage

slp_gas_coefficients(profile_id = NULL, variant = NULL)

Arguments

profile_id

character vector of gas profile identifiers. One or more of "HEF", "HMF", "HKO", "GKO", "GHA", "GMK", "GBD", "GBH", "GWA", "GGA", "GBA", "GGB", "GPD", "GMF", "GHD". Pass NULL (the default) to retrieve all 15 profiles.

variant

character vector of SigLinDe variants to include. One or both of "34" (57 % linear component) and "33" (45 % linear component). Pass NULL (the default) to retrieve both variants. Duplicate values are silently ignored.

Value

A data frame with one row per profile–variant combination and 11 variables:

profile_id

character, gas profile identifier

variant

character, SigLinDe variant ("34" or "33")

A, B, C, D

numeric, sigmoid coefficients

theta0

numeric, pole temperature (40 °C for all published profiles)

mH, bH

numeric, slope and intercept of the space-heating line (Heizgas-Gerade)

mW, bW

numeric, slope and intercept of the hot-water line (Warmwasser-Gerade)

Details

The HKO profile (Kochgasprofil) is a pure sigmoid with no linear component; its mH, bH, mW, and bW are all zero for both variants.

The returned coefficients can be passed directly to slp_gas_siglinde() for custom calculations. When selecting a single profile and variant the result is a one-row data frame, so use [[ ]] or $ to extract scalars:

p <- slp_gas_coefficients("HEF", variant = "34")
slp_gas_siglinde(0, p$A, p$B, p$C, p$D, p$theta0, p$mH, p$bH, p$mW, p$bW)
