andes.routines.tds.TDS#

class andes.routines.tds.TDS(system=None, config=None)[source]#

Time-domain simulation routine.

Some cases may be sensitive to large convergence tolerance config.tol. If numerical oscillation happens, try reducing config.tol to 1e-6.

__init__(system=None, config=None)[source]#

Methods

calc_h([resume])

Calculate the time step size during the TDS.

check_criteria()

Check stability criteria.

do_switch()

Checks if is an event time and perform switch if true.

doc([max_width, export])

Routine documentation interface.

fg_update(models[, init])

Perform one round of evaluation for one iteration step.

init()

Initialize the status, storage and values for TDS.

init_resume()

Initialize a resumed simulation.

itm_step()

Integrate for the step size of self.h using implicit trapezoid method.

load_plotter()

Manually load a plotter into TDS.plotter.

report(**kwargs)

Report interface.

reset()

Reset internal states to pre-init condition.

rewind(t)

TODO: rewind to a past time.

run([no_summary])

Run time-domain simulation using numerical integration.

save_output([npz])

Save the simulation data into two files: a .lst file and a .npz file.

set_method([name])

Set DAE solution method.

streaming_init()

Send out initialization variables and process init from modules.

streaming_step()

Sync, handle and streaming for each integration step.

summary()

Print out a summary of TDS options to logger.info.

test_init()

Test if the TDS initialization is successful.
