Labels correspond the associated described change.

• indicates that some methods were deprecated;
• indicates a breaking change which could impact all users;
• indicates a change in the simulation results that may affect existing tests in your application;
• indicates a new parameter, a new parameter default or a new parameter usage;

📜 Release notes

Dependencies

• Bump powsybl-core to v7.1.0 (#1306 ) Breaking changes are mentioned in the powsyble-core 7.1.0 migration guide

Robustness and accuracy

• Automatic fix of incompatible voltage targets (#1115). This debugging feature helps finding and disabling voltage targets that are mutually incompatible, that can trigger convergence issues (enabled through the parameter fixVoltageTargets ) . The public method VoltageTargetChecker.findElementsToDiscardFromVoltageControl can also be used to display incompatible voltage to users in interactive applications.
• Use of generator equivalentLocalTargetV (new IIDM value) when switching from remote voltage control to local voltage control (#1295)
• Support of fictitious bus injections (#1114) Load flow results may change in IIDM networks that already had non zero values for fictitiousP0 or fictitiousQ0 since they are now taken into account
• Maximum number of shunt sections change per Shunt incremental outerloop (#1297) Introduction of parameter incrementalShuntControlOuterLoopMaxSectionShift Changes can happen when computing load flow with incremental shunt voltage control
• Split Area Interchange Control remaining slack mismatch into several distributions, one per area (#1283)
• Run load flow with main synchronous component mode. The new choice MAIN_SYNCHRONOUS is introduced for LoadFlowParameter componentMode (previously named connectedComponentMode) (#1292)

Performance

• Vectorization of AC EquationSystem (#1275) leading to gain in performance for AC calculation
• Support of multi-thread computation for AC Sensitivity Analysis (#1288) with introduction of a new open sensitivity analysis parameter threadCount

Reports

• Reduce some log levels and send some functional log messages to reports (#1278)
