System¶Originally Contributed by: Clayton Barrows
An example of how to parse add time series data to a System using PowerSystems.jl
For example, a System created by parsing a MATPOWER file
doesn't contain any time series data. So a user may want to add time series to the System
Let's use the 5-bus dataset we parsed in the MATPOWER example
using SIIPExamples
using PowerSystems
using JSON3
pkgpath = dirname(dirname(pathof(SIIPExamples)))
include(joinpath(pkgpath, "test", "2_PowerSystems_examples", "02_parse_matpower.jl"))

For example, if we want to add a bunch of time series files, say one for each load and one for each renewable generator, we need to define pointers to each .csv file containing the time series in the following format (PowerSystems.jl also supports a CSV format for this file)
FORECASTS_DIR = joinpath(base_dir, "forecasts", "5bus_ts")
fname = joinpath(FORECASTS_DIR, "timeseries_pointers_da.json")
open(fname, "r") do f
JSON3.@pretty JSON3.read(f)
end
