The sensitivity-computation command is used to run a sensitivity computation on a network.


$> itools sensitivity-computation --help
usage: itools [OPTIONS] sensitivity-computation --case-file <FILE>
       --factors-file <FILE> [--help] [-I <property=value>] [--import-parameters
       <IMPORT_PARAMETERS>] [--output-file <FILE>] [--output-format <FORMAT>]

Available options are:
    --config-name <CONFIG_NAME>   Override configuration file name

Available arguments are:
    --case-file <FILE>                                 the case path
    --factors-file <FILE>                              sensitivity factors input file
    --help                                             display the help and quit
-I <property=value>                                    use value for given
                                                       importer parameter
    --import-parameters <IMPORT_PARAMETERS>            the importer configuation
    --output-file <FILE>                               sensitivity computation results
                                                       output path
    --output-format <FORMAT>                           the output format [JSON]
    --skip-postproc                                    skip network importer post
                                                       processors (when configured)

Required parameters


Use the --case-file parameter to specify the path of the case file.


Use the --factors-file parameter to specify the path of the sensitivity factors file.

Optional parameters


Use the --import-parameters parameter to specify the path of the configuration file of the importer. It is possible to overload one or many parameters using the -I property=value parameter. The properties depend on the input format. Refer to the documentation page of each importer to know their specific configuration.


Use the --output-file parameter to export the result of the computation to the specified path. If this parameter is not used, the results are printed to the console.


Use the --output-format parameter to specify the format of the result file. Currently, the only supported format is JSON. This parameter is required if the output-file parameter is used.


Use the --skip-postproc parameter to skip the importer’s post processors. Read the post processor documentation page to learn more about importer’s post processors.


To run a sensitivity computation, one has to configure the the componentDefaultConfig module to indicate the implementations to use for:

  • the com.powsybl.sensitivity.SensitivityComputation to use, by setting the SensitivityComputationFactory property
  • the com.powsybl.sensitivity.SensitivityFactorsProvider to use, by setting the SensitivityFactorsProviderFactory property

YAML version

    SensitivityComputationFactory: com.powsybl.sensitivity.mock.SensitivityComputationFactoryMock
    SensitivityFactorsProviderFactory: com.powsybl.sensitivity.JsonSensitivityFactorsProviderFactory

XML version


Note: different sensitivity computation implementations might require specific configurations, in additional config file’s sections.

To learn more about sensitivity factors or available SensitivityFactorsProvider read this documentation page.


The following example shows how to run a sensitivity computation, using the default configuration:

$> itools sensitivity-computation --case-file case.xiidm --factors-file factors.json
