PowerSystems.jl supports serializing/deserializing data with JSON. This notebook
provides an example of how to write and read a System to/from disk.
Let's use a dataset from the tabular data parsing example
using SIIPExamples
pkgpath = dirname(dirname(pathof(SIIPExamples)))
include(joinpath(pkgpath, "test", "2_PowerSystems_examples", "02_parse_matpower.jl"))
