objective_mc_variable_pg_cost(pm::AbstractUnbalancedPowerModel)

adds pg_cost variables and constraints

objective_variable_pg_cost(pm::AbstractUnbalancedIVRModel)

adds pg_cost variables and constraints for the IVR formulation

calc_max_cost_index(data::Dict{String,<:Any})

Computes maximum cost index

simplify_cost_terms!(data::Dict{String,<:Any})

trims zeros from higher order cost terms

calc_pwl_points(ncost::Int, cost::Vector{<:Real}, pmin::Real, pmax::Real; tolerance=1e-2)

• the first and last points are strickly outside of the pmin-to-pmax range
• pmin and pmax occur in the first and last line segments.

calc_cost_pwl_lines(comp_dict::Dict)

compute lines in m and b from from pwl cost models data is a list of components. Can be run on data or ref data structures

standardize_cost_terms!(data::Dict{String,<:Any}; order=-1)

ensures all polynomial costs functions have the same number of terms
