convertscenariounits(
    path::String; 
    energy_multiplier::Float64 = 1.0, 
    power_multiplier::Float64 = 1.0, 
    cost_multiplier::Float64 = 1.0, 
    emissions_multiplier::Float64 = 1.0, 
    quiet::Bool = false
)

Converts units of measure in the scenario database at path. Quantities denominated in energy units are multiplied by energy_multiplier, quantities denominated in power units are multiplied by power_multiplier, quantities denominated in cost units are multiplied by cost_multiplier, and quantities denominated in emissions units are multiplied by emissions_multiplier. The quiet argument suppresses non-essential status messages.

This function assumes that consistent energy and power units are used across regions, and it converts both parameter and variable tables. It also converts default values in the DefaultParams table.

createnemodb(path::String;
defaultvals::Dict{String, Float64} = Dict{String, Float64}(),
foreignkeys::Bool = false)

Creates an empty NEMO scenario database in SQLite. If the specified database already exists, drops and recreates NEMO tables in the database.

Arguments

• path::String: Full path to the scenario database, including the file name.
• defaultvals::Dict{String, Float64} = Dict{String, Float64}(): Dictionary of parameter table names and default values for val column.
• foreignkeys::Bool = false: Indicates whether to create foreign keys within the database.

dropdefaultviews(db::SQLite.DB)

Drops all views in db whose name ends with ""_def"".

dropresulttables(db::SQLite.DB, quiet::Bool = true)

Drops all tables in db whose name begins with ""v"" or ""sqlite_stat"" (both case-sensitive). The quiet parameter determines whether most status messages are suppressed.

logmsg(msg::String, suppress=false, dtm=now()::DateTime)

Prints a log message (msg) to STDOUT. The message is suppressed if suppress == true. dtm determines the date and time included in the printed message.

Examples

julia> using Dates

julia> logmsg("Test message", false, DateTime(2020))
2020-01-Jan 00:00:00.000 Test message

setparamdefault(db::SQLite.DB, table::String, val::Float64)

Sets the default value for a parameter table in a NEMO scenario database.

Arguments

• db::SQLite.DB: Scenario database containing the parameter table.
• table::String: Table name (case-sensitive).
• val::Float64: Parameter value (must be a floating-point number).

find_infeasibilities(m::JuMP.Model,
    silent_solver::Bool=false
)

Returns a Vector of constraint data for constraints in m that cause infeasibility. silent_solver suppresses output from the solver for m.

Arguments

• m::JuMP.Model: Model to check for infeasibility. Should be a NEMO model created with calculatescenario.
• silent_solver::Bool = false: Suppresses output from the solver for m.
