Run the voltage initializer

Prerequisites

For now the voltage initializer tool rely on Ampl and Knitro. the binary knitroampl must be in your PATH.

The pypowsybl config file (generally located at ~/.itools/config.yaml) must define the ampl section to find your dynawaltz installation and defaults parameters Here is an example of a simple config.yaml file.

ampl:
    homeDir: PATH_TO_AMPL

Quick start

Here is a simple starting example:

import pypowsybl as pp
import pypowsybl.voltage_initializer as v_init
params = v_init.VoltageInitializerParameters()
n = pp.network.create_eurostag_tutorial_example1_network()
some_gen_id = n.get_generators().iloc[0].name
params.add_constant_q_generators([some_gen_id])
some_2wt_id = n.get_2_windings_transformers().iloc[0].name
params.add_variable_two_windings_transformers([some_2wt_id])

params.set_objective(VoltageInitializerObjective.SPECIFIC_VOLTAGE_PROFILE)

results = v_init.run(n, params)
results.apply_all_modification(n)

print(results.status())
print(results.indicators())
