📜 Release notes

Dependencies

Bump powsybl-core version to 7.3.0 (#1392, #1448) Breaking changes are mentioned in the powsyble-core 7.3.0 migration guide
Migrate to powsybl-parent v29 and fix code to follow new Checkstyle rules (#1439)

Fix DC nodes voltage initialization in ACDC load flow (#1406)
Option to disallow Non-Linear Shunt Compensator section zero (#1419) This can be done using parameter allowNonLinearShuntZeroSection (default value keeps the previous behavior)
Fix JSON update of Security and Sensitivity Parameters extensions (#1410) Tests using JSON parameters import can change
Fix DC Load Flow running slack distribution for epsilon mismatch (#1389) Slack distribution in reports may be impacted
Throw exception when having DcSwitch with non zero resistance (#1447) (before introduction in a future release)

Fix state monitors in security analysis with operator strategies (#1420)
Add version and parameters logging for Security and Sensitivity Analysis Providers (#1400)

Support preventive actions in DC sensitivity analysis (#1383)
Support generator and load actions in DC sensitivity analysis (#1425)
Support SHUNT_COMPENSATOR_SUSCEPTANCE variable type in AC Sensitivity Analysis (#1396)
Support BRANCH_RESISTANCE, BRANCH_REACTANCE and BRANCH_ADMITTANCE variable types in AC Sensitivity Analysis (#1438)
Support SVC_PILOT_POINT_TARGET_VOLTAGE variable type in AC Sensitivity Analysis (#1444)
Use lowImpedanceThreshold parameter in Sensitivity analysis (and add warning logs for unsupported parameters) (#1411) Sensitivity analysis that did not take into account this parameter before can have different results
Fix PST action in DC sensitivity analysis (#1418)

Add support of network cache for DC load flow (#1386): the fast restart feature can be used to avoid reloading the network for multiple load flow computations with a network that has only minor changes
Fast restart: Add support of active power update of Load, LCC, VSC and BoundaryLine (#1427)
Incremental Transformer Voltage Control: filter insensitive controllers from the regulation in order to avoid additional unecessary outer loops iterations (#1417)
Filtering monitored results in N-1 state result to limit memory usage (#1398) this can be used through the new SecurityAnalysis parameter modifiedMonitoredElementsParameters
Remove redundant outer loop executions at load flow ending (#1414)

Remove powsybl-loadflow-results-completion dependency (#1387)
Add contributing and security references to the readme (#1382)
Add common config for tests (to change MatrixFactory in all tests) (#1403)
Refactor network cache to allow future extension of fast restart to sensitivity analysis (#1421)
Fix ComponentMode parameter having category "None" instead of "Performance" (#1435)
Remove use of deprecated LimitViolation() constructor (#1443)
