Data parsing

ProxAL.parse_file — Function

parse_file(datafile::String)

Parse MATPOWER or PSSE instances using ExaPF's parsers. Return full dataset as Dict{String, Array{Float64, 2}, with entries

"bus": specifications for all buses in the network
"branch": specifications for all branches in the network
"gen": specifications for all generators in the network
"costs": costs coefficients.
"baseMVA": baseMVA of the network

ProxAL.RawData — Type

ProxAL.opf_loaddata — Function

opf_loaddata(
    raw::RawData;
    time_horizon_start::Int=1,
    time_horizon_end::Int=0,
    load_scale::Float64=1.0,
    ramp_scale::Float64=0.0,
    corr_scale::Float64=0.1,
    lineOff=Line(),
    genOff::Vector{Int}=Int[],
)

Loads the multi-period ACOPF instance data from raw with the time horizon defined to be [time_horizon_start, time_horizon_end]. Note that time_horizon_end = 0 indicates as many as possible (the number of columns in raw.pd_arr minus time_horizon_start - 1).

All loads in all time periods will be multiplied by load_scale. The ramp_scale is the factor which multiplies the ramp rate to get generator ramping $r_g$ (see NOTE below). The corr_scale is the factor which multiplies $r_g$ to get generator ramping for corrective control. These are set in ModelInfo. See Model parameters.

lineOff is a transmission line that can be deleted to represent a contingency.

genOff is a vector of generator indices that can be turned off to represent a contingency.

NOTE: If raw.genfuel_arr is undefined for generator $g$, then the ramp rate is set equal to $p_{g}^{max}$. Otherwise, the ramp rate is set based on the genfuel type as follows. coal => 3 wind => 45 solar => 200 ng => 35 nuclear => 20 hydro => 150 default => 3 (same as coal)
