andes.utils.snapshot

Utility functions for saving and loading snapshots.

Code Examples:

1. Setup base case and save the snapshot for once:

import andes

ss = andes.run(andes.get_case("ieee14/ieee14_linetrip.xlsx"))
ss.Toggle.u.v[:] = 0  # turn off line trips for the base case
xy = ss.TDS.init()

andes.utils.snapshot.save_ss("ieee14_snapshot.pkl", ss)

2. For every scenario afterwards, load the snapshot and apply disturbances:

import andes

ss = andes.utils.snapshot.load_ss("ieee14_snapshot.pkl")

# apply specific disturbances
ss.GENROU.omega.v[0] = 1.02

ss.TDS.run()

Functions

load_ss(path)	Load an ANDES snapshot and return a System object.
save_ss(path, system)	Save a system with all internal states as a snapshot.
